Description

  The present invention is a file or folder management device having a function of automatically assigning a name when a file or folder is newly created, and in particular, a music data data file is created in an electronic music device such as an electronic musical instrument. File name automatic assignment function.

Conventionally, when a new data file is created in an electronic music apparatus such as an electronic musical instrument, a technique is known in which the system automatically assigns a file name to the newly created file. For example, in the apparatus described in Patent Document 1 below, when recording audio data, a file name consisting of a predetermined character string (for example, “Song”) and a number n is automatically assigned to a newly created file. In addition, when another audio data is recorded on the file having the automatically assigned file name and recorded (overdubbing), a backup file of the original file is automatically created. Thus, a file name with another predetermined character string “Bn” added to the end of the original file name is automatically created. Here, “n” included in the file name is a positive integer, and each time audio data is newly recorded, a file name (“Song1”, “Song2”,... -) Was automatically created, and for the backup file with the file name “Song1”, file names “Song1_B1”, “Song1_B2”... Having numbers indicating the generation order of the backups were automatically assigned. According to such a naming method, by placing the word “Song” in the character string portion of the automatically assigned file name, it is possible to indicate that the file is a file having data relating to music, In addition, there is a merit that the creation order of files and the generation order of backup can be intuitively understood from the numerical part.

  A rough procedure for creating a new file in the electronic music apparatus is, for example, as follows. First, in response to a new file creation instruction, an empty file having a file name is automatically created, and data (audio data, MIDI performance data, etc.) to be recorded is written in the empty file. Thereafter, the user can change the name automatically given the file name of the file into which the data has been written to any other name. That is, according to such a procedure, a newly created file is temporarily stored with an automatically assigned file name.

  The newly created file is stored in a storage medium provided in the electronic music device. When reading a specific file from a group of files stored on a storage medium, all the files stored in the folder are displayed in a list on the display unit, and the user can find a desired file from the displayed list. It is common to make it. In the list, the files are sorted (sorted) in the order of file names, and the user can search for the target file in accordance with the sort order (arrangement order) of the files. The file sorting order follows a predetermined sorting rule that defines the ordering relationship of character groups (alphabetic characters, kana characters, kanji characters, numbers, symbols, etc.) that can be used as file names. The sort rule defines the order relationship of character groups that can be used as file names in accordance with, for example, alphabetical order, kana-syllabary order, and numerical magnitude relationship.

  In the list display, files that are automatically assigned file names and files that are given file names by the user are not distinguished, and are sorted in a sort order according to a predetermined sort rule. The automatic file name assignment function does not create a file name in consideration of the sort order. For this reason, when a large number of files are stored in the device, a newly created file (a file with an automatically assigned file name) is buried in a large number of files, and a newly created file is created. Sometimes it was difficult to figure out where the file was in the list. That is, according to the conventional technique, when a large number of files are stored in the apparatus, it is difficult to find a newly created file.

  The present invention has been made in view of the above points, and it is possible to easily manage a file or a folder having a name automatically given by an automatic assignment function from a number of files or folders. An object is to provide an apparatus.

  The file or folder management device according to the present invention stores one or a plurality of files for storing a data aggregate and a folder for storing a plurality of the files, and each of the files and folders Is a storage means that is given a unique name, and a file group or folder group that is stored in the storage means in accordance with a sorting rule that defines the order relationship of all characters that can be used in the names of the files and folders. Sorting means for sorting the files in the order of names, creating means for creating a new file or folder in the storage means, and for the file or folder newly created by the creating means, the sorting rule An assigning means for automatically assigning a name beginning with a character defined at the beginning or end of the order relation; Characterized in that it comprises.

  According to this, the creation means creates a new file or folder in the storage means, and the assigning means creates a new file or folder in relation to the order of all characters that can be used in the file and folder names. The name having the character defined at the beginning or the end of the order relation of all the characters is automatically given by the sorting rule that defines Therefore, when the file group or folder group is sorted in the name order by the sorting means, the newly created file or folder is positioned at the head or the tail of the sort order.

  Further, the present invention can be configured and implemented not only as an apparatus invention but also as a method invention. Further, the present invention can be implemented in the form of a program of a processor such as a computer or a DSP, or can be implemented in the form of a storage medium storing such a program.

  According to the present invention, for a newly created file or folder, the sorting rule that defines the order relation of all characters that can be used in the names of the files and folders is placed at the beginning or end of the order relation of all the characters. By automatically assigning a name having a defined character at the beginning, the newly created file or folder is positioned at the beginning or end of the sort order when the file group or folder group is sorted in name order. Therefore, a file or folder having a file name automatically assigned by the assigning means is clearly distinguished from other file name groups when the file group or folder group is sorted. Therefore, even when a large number of files or folders are stored in the storage means, a file or folder newly created from the large number of files or folders, that is, a file name automatically assigned by the assigning means. There is an excellent effect that a file or a folder can be easily found.

  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a block diagram showing an example of an electrical hardware configuration of an electronic music apparatus to which a file or folder management apparatus according to an embodiment of the present invention is applied. As the electronic music device, for example, an electronic organ, an electronic piano, an electronic musical instrument such as a synthesizer can be applied.

  As shown in FIG. 1, the electronic music apparatus includes a microcomputer including a CPU 1, a ROM 2 and a RAM 3, a performance operator 4 for performing a performance input (pronunciation instruction) operation, and a performance input performed by the performance operator 4. A performance detection circuit 5 for detecting an operation, a setting operator 6 for making various settings, an operation detection circuit 7 for detecting an operation of the setting operator 6, and a display for displaying various information 8, a display control circuit 9 for controlling the display of the display 8, a storage device (storage means) 10, a tone generator unit 11 that electronically generates a tone signal, and a tone signal generated by the tone generator unit 11 A sound system 12 for sound generation and a communication interface 13 are included, and each unit is connected to each other via a data and address bus 1B.

  The CPU 1 executes a control program stored in the flash memory 2 or the RAM 3 and controls the overall operation of the electronic music device. In this embodiment, the new file creation process shown in FIG. 3 and the file list display process shown in FIG. 5 described later are configured and implemented by a software program executed by the CPU 1.

  The performance operator 4 may be any type of operator as long as the user performs a performance operation. For example, a keyboard unit composed of a plurality of keys each assigned a pitch of a musical tone. Can be applied. The user performs a performance operation using the performance operation element 4 to generate a musical sound corresponding to the performance operation from the sound system 12, or the contents of the performance operation are stored in a data file of music data for one song. Can be stored in the storage device 10. The setting operator 6 is a group of switches arranged on the main body panel of the electronic music apparatus for performing various settings, and operates switches for selecting parameters such as timbre and various functions and GUI parts on the display 8. For example.

  The display 8 is constituted by a liquid crystal display panel (LCD) disposed on the main body panel of the electronic music apparatus. Various kinds of control screens are displayed on the display 8, and GUI parts (such as operation element images) for accepting various operations from the user, various character information, and the like are displayed on the various control screens. The operation of the GUI component displayed on the display 8 may be performed using the setting operator 6. Or the display 8 may be comprised with the touchscreen type display provided with the mechanism which performs input operation by a user touching the display on a screen. The display 8 is used to display a file name list as will be described in detail later. Here, since the display 8 is arranged on the main body panel of the electronic music apparatus, it is required to reduce the screen size as much as possible, that is, the area where information can be displayed is physically limited. Note that it is constrained.

  The storage device 10 is, for example, a conventionally known appropriate storage medium such as a semiconductor memory such as a hard disk, FD (flexible disk or floppy disk (trademark)), CD (compact disk), DVD (digital multipurpose disk), flash memory, or the like. And its driving device. The storage medium may be removable from the main body of the electronic music device, or may be built in the electronic music device.

  The storage device 10 stores a plurality of music files that store music data. The music data for one song is a collection of performance data having an appropriate format such as MIDI performance data. The user can appropriately classify and store a plurality of files stored in the storage device 10 into folders (directories). A plurality of folders can be created in the storage device 10. Each file and folder in the storage device 10 is given a unique name. The name of the file and folder can be given by the user with an arbitrary character string, or the system can automatically give a name with a predetermined character string by the automatic assignment function described later. As is well known, a user can perform operations such as creating a new file or folder, moving a storage location, copying, or deleting.

  The tone generator unit 11 includes a tone generator circuit that generates a musical tone signal and an effect applying circuit that imparts an effect to the musical tone signal generated by the tone generator circuit. Then, a musical sound signal is generated based on performance data (MIDI performance data) generated by sequencer reproduction (automatic performance) of a music data file stored in the storage device 10. The musical sound signal generated by the sound source unit 11 is generated from a sound system 12 including an amplifier and a speaker.

  In addition, the electronic music apparatus may include a communication interface (communication I / F) 13 for communicating data with an external device. As the communication I / F 13, a music-dedicated wired I / F such as a MIDI interface for communicating MIDI data with an external MIDI device, a general-purpose short-distance wired I / F such as USB and IEEE 1394, and a general-purpose such as Ethernet (trademark) One or a plurality of interfaces such as a network I / F or a general-purpose short-range wireless I / F such as a wireless LAN or Bluetooth (trademark) can be mounted. The electronic music apparatus connects an external storage device (for example, a USB memory) via the communication I / F 13, and saves the file to the connected external storage device or reads the file stored in the external storage device You can also.

  The electronic music apparatus having the above configuration automatically assigns a file name consisting of a predetermined character string to a newly created file when a file to be stored in the storage device 10 is newly created. It has a function. A function itself for automatically assigning a file name to a newly created file has been conventionally known. As will be described in detail later, the present invention has a great feature in naming file names that are automatically assigned by the automatic assignment function. For the detailed operation of the new file creation process, refer to the description of FIG.

  In this embodiment, as shown in FIG. 2A, the file name automatically given to the new file by the file name auto-assignment function has a predetermined symbol “!” At the beginning, and a predetermined character string “!” “song” followed by a character string with a three-digit number string “nnn” appended to the end. “N” represents a positive integer. The exclamation point symbol “!” Added to the beginning of the file name is the end of the order relationship (sort order in ascending order) of all character groups that can be used as the file name according to the predetermined sorting rule applied in this embodiment. Is the character defined in. Therefore, the file name consisting of the head part “!”, The character string “song”, and the three-digit number string “nnn” is sorted when a plurality of file names are sorted in ascending order according to the predetermined sorting rule. It is located at the end of the file name column.

  FIG. 2B is a diagram for explaining the sorting rule applied in this embodiment, and is a group of file names sorted in order of name according to the sorting rule of this embodiment, and FIG. Each character string indicated by reference numerals 14 to 17 is an example of a file name, and each file name is sorted in ascending order. The sort function for sorting files (or folders) in the storage device 10 in the order of names is provided as one of the functions for controlling the storage device 10 by a control program executed by the CPU 1. Conventionally known. The sort rule used for the processing of the sort function is to sort all file names in a folder in the order of their names (alphabetic characters, kana characters, kanji characters, This is a rule that defines the order relationship between numbers and symbols. In the electronic music apparatus, for example, a table describing a sort rule is stored in the ROM 2, and a sort process according to the sort rule is executed with reference to the table. This sorting function corresponds to the sorting means described in claim 1. Note that “ascending order” means that file names are arranged in the order of the characters defined in the higher order by the sorting rule and the characters defined in the lower order. This is the order in which they are arranged in the order of 50 tones for kana characters and A to Z for alphabetic characters. Conversely, arranging the file names in the order of the characters defined in the lower order to the characters defined in the upper order is called “descending order”.

  In the sorting rule of this embodiment, as shown in FIG. 2 (b), the file name is represented by “first group (reference numerals 14a, 14b)” and “second group (reference numeral 15a) depending on the first character. ˜15d) ”,“ third group (reference numerals 16a to 16d) ”, and“ fourth group (reference numerals 17a to 17c) ”. The group in the first group is the upper group in the sort order, and is followed by the groups in the second group, the third group, and the fourth group in ascending order.

  In the “first group” group, file names 14a and 14b beginning with a symbol corresponding to a predetermined first type of half-width symbol group are classified. In this embodiment, the first type of half-width symbol group includes a half-width underscore symbol “_”, a half-width space symbol, and the like. In the example of FIG. 2B, a half-width underscore such as “_SSS” is used. File names beginning with the score symbol “_” correspond to the “first group” group. In the “second group”, file names starting with half-width alphanumeric characters such as “abc001”, “abc002”, and the like are classified into 15a to 15d. The “third group” group includes file names 16a to 16d that start with double-byte characters, such as “Aiueokaki Kakesashi Soseso 001.mid”.

  The “fourth group” group is the last group in the ascending order, and the second half-width symbol group including the exclamation mark symbol “!” Is classified into this group. The exclamation mark symbol “!” Is a character defined at the end of the ascending sort order in the “fourth group” group. Therefore, the file name having the exclamation mark symbol “!” At the head is positioned at the end of the sorted file name column when a plurality of file names are sorted in ascending order according to the sorting rule. An important point in the sort rule applied to this embodiment is that the exclamation mark symbol “!” Is defined at the end of the sort order in ascending order. Therefore, the order relation of characters that can be used as other file names may be determined in accordance with the definition of an appropriate character code adopted in a general computer, for example.

  Therefore, as shown in FIG. 2 (b), a file name automatically assigned by the file name automatic assignment function (a file composed of a predetermined symbol “!”, A character string “song”, and a three-digit number string “nnn”). Name) is always located at the end (or near the end) of the file group when the file group of the storage device 10 is sorted in ascending order by name. That is, the file names automatically assigned by the file name automatic assignment function are clearly distinguished from other file groups by their positions when sorted. Therefore, the user can easily find a file name corresponding to a newly created file from among a large number of file names.

  In FIG. 2B, the file names “! Song001”, “! Song002”, and “! Song003” automatically given by the file name auto-assignment function are illustrated as file names corresponding to the “fourth group” group. ing. In each of the automatically assigned file names 17a to 17c, the exclamation mark symbol "!" And the character string portion "song" are common to each other, and these files store music data by the character string portion "song". Can indicate to the user that it is a file. Each file name can be identified by the last three digits of the string name “001”, “002”, and “003”. Basically, a serial number obtained by adding 1 of the numerical value (number) of the numeric string portion of the previously created file is assigned to the numeric string portion. That is, each time a new file is created, a file name having a serial number corresponding to the file creation order is assigned to the new file. Therefore, when the order of file names when sorted in ascending order is limited to the file names 17a to 17c automatically assigned by the file name automatic assigning function, the file name of the most recently created file is shown. 17c is located at the end. Therefore, a newly created file is basically added to the end of the file name group sorted in ascending order. Therefore, it is easy to find the most recently newly created file from the sorted file group.

  Note that a file name having a “three-digit number string” at the end is not limited to an automatically assigned file name. For example, such a “three-digit number string” is often numbered for the file names of music data files of different takes (different versions) of the same music. For example, in FIG. 2B, when the performance of the same song as the file name 15a “abc001” is recorded in another take, the user adds the file name 15b “abc002” to the file in which the performance of the other take is recorded. Will be attached. In this case, the first alphabet character string portion (“abc”) is often a word indicating a song title, and the difference between individual files can be distinguished by the number portion at the end. Therefore, in such a file name, the two elements of the leading character string portion and the trailing numeric string portion function as main elements for identifying individual files. In FIG. 2B, file names 16a to 16d are examples of file names with an extension added to the end of the character string. The file type (file format) can be identified by the extension given to the end of the character string. Thus, the extension in the file name will also serve as the main element that identifies individual files.

  FIG. 3 is a flowchart showing an example of a procedure for new file creation processing. With reference to FIG. 3, an example of an operation of automatically assigning a file name by the automatic file name assignment function when creating a new file will be described. This new file creation process is started, for example, when a user records a manual performance using the performance operation element 4. That is, a new file is created to store performance data generated by manual performance. The recording start instruction may be performed using, for example, the setting operation element 6 on the main body panel of the electronic music apparatus or the GUI object displayed on the display 8. In addition, before the process for creating a new file described below is started, one folder to which a new file is to be created is specified.

  In step S1, it is checked whether a file having a file name assigned by the automatic assignment function exists in a folder in which a new file is created. In this embodiment, the file name assigned by the automatic assignment function is a file name composed of the exclamation mark symbol “!”, The character string “song”, and the “three-digit number string” as described above. If there is no file having a file name corresponding to the file name assigned by the automatic assignment function in the folder (NO in step S1), an exclamation mark symbol “!”, A predetermined character string “song”, A new file with a file name “! Song001” consisting of an initial value “001” of a three-digit number string is created (step S2).

  On the other hand, if a file having a file name corresponding to the file name assigned by the automatic assignment function already exists in the folder (YES in step S1), “3” of the file name assigned by the existing automatic assignment function. All of the "digit string" part is checked to check whether there is any "three-digit numeral string part" that has reached the limit value "999" (step S3). If the maximum value of the existing “three-digit number sequence portion” has not reached “999” (NO in step S3), the “three-digit number sequence” of the file name automatically given to the newly created file "Is a value obtained by adding 1 to the numerical value of the maximum number (the last number) in the existing number string portion, that is, a number consecutive to the maximum number (step S4). As a result, until the number string portion of the file name given by the automatic assignment function in the folder reaches “999”, “! Song001”, “! Song002”, “! Song003”, etc. Each time a file is created, a file name (“! Song“ nnn ””) having a serial number corresponding to the file creation order is automatically given.

  In the folder, when the “3-digit number string” of the file name given by the automatic assignment function has already reached the limit value “999” (YES in step S3), the existing “3-digit number string” Is checked to see if there is an unused number (empty number) among the initial value “001” to the limit value “999” of the 3-digit number string (step S4). An unused number (empty number) occurs when the user changes the automatically assigned file name to another file name or deletes the file. If there is an unused number (YES in step S6), the unused number (empty number) value is used for the "three-digit number string" portion of the file name automatically assigned to the newly created file. (Step S7). As a result, even after the number string portion of the file name given by the automatic assignment function in the folder reaches “999”, the file consisting of the character string “! Song“ nnn ”” is newly created. Name can be given. In addition, when there are a plurality of unused numbers, they are used in order from the smallest number.

  On the other hand, when all of the initial value “001” to the limit value “999” are used for the existing “three-digit number string” and there is no space (NO in step S6), the newly created file is Since a unique file name cannot be automatically assigned, the process ends without creating a new file. At this time, it is preferable to display on the display 8 a warning to the user that “a new file cannot be created”.

  By the above step S2, S4 or S7, a file having a file name consisting of the exclamation mark symbol “!”, The character string “song”, and the three-digit number string “nnn” as shown in FIG. Newly created. At this point, data is empty in the newly created file. The user can perform arbitrary editing on the newly created file (step S8). In this embodiment, the “arbitrary editing” is a process of writing MIDI performance data representing a manual performance performed by the user using the performance operator 4 to the newly created file. As a result, MIDI performance data representing a manual performance performed by the user using the performance operator 4 is stored in the newly created file as music data for one song. Thus, a data file having a file name consisting of the character string “! Song“ nnn ”” is newly stored in the folder of the storage device 10. The new file creation process described here corresponds to the creation means described in claim 1, and the processes of steps S <b> 2, S <b> 4, and S <b> 7 correspond to the grant means described in claim 1.

  Note that the file name newly created by the new file creation process, that is, the automatically assigned file name, is stored in the storage device 10 and can be changed by the user to another name. After the name change, the file is sorted based on the changed file name. It should be noted that when the user assigns a file name, the predetermined character “!” May not be used at the beginning of the file name. Thereby, confusion between the file name given by the user and the file name automatically given can be avoided.

  In the electronic music apparatus, when reproducing a data file of music data stored in the storage device 10, changing the file name of the data file, or performing an operation such as re-editing, copying or deleting the data file The user has to find one specific file from among a large number of data file groups stored in one of the plurality of files in the storage device 10.

  In this electronic music device, when searching for a desired file from the file group stored in the storage device 10, a list of a plurality of file names stored in any one of the file groups stored in the storage device 10 is displayed. The displayed file name list is displayed on the display 8, and a desired file can be found from the file names displayed in the list. FIG. 4A shows a display example of the file name list, and the file names exemplified in FIG. 2B are displayed in the file name list. In FIG. 4A, file names 16a to 16d are displayed in a form in which a part of the character string constituting the file name is omitted. This is because the file names 16a to 16d are too long to display the entire file name in the display area of the display 8. As will be described in detail below, the file name list according to this embodiment is characterized in that it is omitted when a part of a character string constituting the file name is omitted.

  FIG. 5 is a flowchart showing an example of the procedure of the file name list display process. The file name list display process is performed for any one of a plurality of folders set in the storage device 10. Therefore, the user designates a folder (directory) to be displayed as a file name list from a plurality of folders set in the storage device 10 (step S10). For example, a list of options (such as folder icons) for selecting one of a plurality of folders set in the storage device 10 is displayed on the display 8, and the user is allowed to specify a desired folder from the options. Thus, an operation for designating a folder to be displayed as a file name list may be realized. When the user designates a folder to be displayed as a file name list, a list of all file names stored in the designated folder is acquired (step S11). By performing the processing of steps S13 to S19 described below, the display form of all the file names in the acquired list in the file name list is determined. The process in step S12 is a determination process for performing the processes in steps S13 to S19 for each of all the file names in the acquired list.

  First, in step S13, processing for calculating a display width WF necessary for displaying a file name is performed. The display width (number of dots) WF of the file name is the width of the display area necessary when displaying all the character strings constituting the file name on the display 8. In this embodiment, in the display of characters on the display 8, a monospaced font (font with a fixed horizontal width for each character) is used for displaying full-width characters, and a proportional font (optimum for each character) is used for displaying half-width characters. Font with a horizontal width). Accordingly, the file name display width WF is determined based on the number of characters in the character string constituting the file name and the type of each character.

  In step S14, the file name display width WF calculated in step S13 is compared with the file name displayable width (number of dots) WD on the display 8. The file name displayable width WD is a width in which one file name can be displayed in the file name list displayed on the display 8 (see FIG. 4A). As already described, the screen size of the display 8 is restricted to a relatively narrow width because the display 8 is arranged on the main body panel of the electronic music apparatus. Accordingly, the file name displayable width WD of the file name list displayed on the display 8 must be limited to a relatively narrow width. For this reason, the file name display width WF may be larger than the file name displayable width WD. 4B shows a comparison between the display widths WF of the file name 15d, the file name 16a, and the file name 16c exemplified in FIG. 2B and the displayable width WD of the display 8. In FIG. As is clear from FIG. 4B, the display width WF of a long file name such as the file name 16a and the file name 16c exceeds the displayable width WD of the display 8.

  When the display width WF of the file name is larger than the displayable width WD of the display 8 (YES in step S15), a process for changing the display form of the file name is performed by the process from step S16. Here, the change of the display form of the file name means that a part of the character string constituting the file name is omitted according to a predetermined rule described below, so that the display width WF of the file name is set to the displayable width of the display 8. It is to reduce the width to fit in the WD. In this embodiment, the rule for omitting a part of the character string constituting the file name is to leave the head part of the file name, the “specific character string” part described below, and the extension part, The other part is omitted. In the electronic music apparatus, for example, tables describing rules for omitting a part of a character string constituting a file name are prepared in the ROM2 to RAM3. With reference to the tables, in accordance with the rules, step S16 and subsequent steps are performed. This process (a process for changing the display format of the file name) is executed.

  If the file name display width WF is equal to or smaller than the file name displayable width WD of the display 8 as in the file name 15d shown in FIG. 4B (NO in step S15), the entire name of the file name is saved as a file. Since it can be displayed on the name list, it is not necessary to change the display format of the file name described below.

  If the display width WF of the file name is larger than the displayable width WD of the display 8, in step S16, a process for detecting a specific character string from the character string constituting the file name is performed. Here, the specific character string to be detected is a character string predetermined as information necessary for identifying individual files, and in this embodiment, a “three-digit number string” is used. Applicable. As described above, the “three-digit numeric string” often functions as an important element for identifying individual files.

  For example, the file name 16a “aiueokikikakusashisoseso001.mid” shown in FIG. 4B has a display width WF larger than the displayable width WD of the display 8, and a specific character string (this In the embodiment, the file name includes “three-digit number string”) (YES in step S17). With respect to such a file name, the display width WF is displayed on the display 8 while leaving the head portion of the file name, a specific character string (three-digit number string “001”), and the extension portion “.mid”. The display form of the file name is changed so as to be within the displayable width WD (step S18 in FIG. 5). Specifically, by replacing some character strings immediately before (left side) of a three-digit number string with an ellipsis (three-point reader “...”), “Aiue…” shown in FIG. The file name is abbreviated as “001.mid”. Note that the character range (number of characters) to be left at the beginning of the file name, in other words, the character range to be replaced with an ellipsis, is the width necessary to display the specific character string “001” and the extension “.mid” part. It is determined according to the displayable width WD of the display 8.

  In addition, the file name 16c “Ichiro Nihongo Niwawa waka ABC.mid” illustrated in FIG. 4B is a file name whose display width WF is larger than the displayable width WD of the display 8, Is not included ("three-digit number string") (NO in step S17). With respect to such a file name, the display form of the file name is changed so that the display width WF is within the displayable width WD of the display 8 with the head portion of the file name and the extension “.mid” remaining. 5 step S19). Specifically, by replacing some character strings (character strings on the left side) immediately before the extension “.mid” with ellipses, “Iroha niho .... mid” shown in FIG. The file name is abbreviated as follows.

  By performing the processes of steps S13 to S19 for all the file names included in the designated folder, the display form of the file names in the list display is determined for all the file names. In step S20, a file name list obtained by sorting all files included in the folder in the order of file names is displayed on the display 8. The user may be able to select the sorting direction of the file name list displayed on the display 8 in either ascending order or descending order. An example of the file name list displayed on the display 8 at step S20 is as shown in FIG. In FIG. 4A, the file names 16a to 16d whose file name display width WF is larger than the displayable width WD of the display 8 are character strings that appropriately constitute the file name by the processing of S13 to S19. Part is omitted. That is, the file names 16a, 16b, and 16d are omitted except for the first part of the file name, the specific character string (three-digit number string), and the extension part “.mid”. Yes. Further, the file name 16c is omitted except for the head part of the file name and the extension part “.mid”. On the other hand, as for the file name 15d and the file names 17a to 17c, the entire file name is displayed for the file names whose file name display width WF is within the displayable width WD of the display 8. If the display width WF of the file name is larger than the displayable width WD of the display 8, but the specific character string (three-digit number string) and the extension are not included in the file name, the file name An appropriate display form conventionally known, such as an abbreviated display that leaves only the top part, may be applied.

  For example, the file name 16a and the file name 16b are named such that each of the file names has a common kana character string at the head part, and each file name is identified by a numeric string part that follows. As already mentioned, this is a naming pattern often found in naming files that record recordings of different versions of the same song. In this case, the two elements, the first kana character part and the last digit string part, Serves as the primary element for identifying individual files. Therefore, as shown in FIG. 4A, on the file name list, the head part of the file names 16a and 16b, the specific character string (three-digit number string), and the extension part “.mid” are left. By displaying the file name in a form that omits the other parts, the user can reliably identify individual files even if the file name on the list is displayed in a form that omits a part of the character string. can do.

  Also, as already described, according to the sorting rule applied in this embodiment, the exclamation mark symbol “!” Is defined at the end of the order relationship (sort order in ascending order) of all characters that can be used as file names. Symbol. Therefore, the file names automatically assigned to the newly created files, that is, the file names 17a to 17c having the exclamation mark symbol “!” At the head are located at the end of the file name list. It is clearly distinguished from the file name group. Further, among the file names having the exclamation mark symbol “!” At the head, the file number having the larger “three-digit number string” portion at the end is positioned at the end of the list. Therefore, basically, the latest newly created file is located at the bottom (or near the bottom) of the list. Therefore, the user can easily find a newly created file from the file name list.

  As described above, according to this embodiment, when a file is newly created, the characters defined at the end of the order relationship (sort order in ascending order) of all characters that can be used as file names by the sort rule. When a file group stored in the storage device 10 is sorted in ascending order of the file name, the newly created file is always at the end of the file group (or near the end). ) Will be located. That is, when the file group is sorted, the automatically assigned file name is clearly distinguished from other file name groups. By automatically assigning such a file name to a newly created file, even if a large number of files are stored in the storage device 10, a newly created file from the large number of files, In other words, it has an excellent effect that a file having a name automatically assigned by the automatic assignment function can be easily found.

  Further, according to this embodiment, when the file name list of the file group stored in a certain folder is displayed on the display 8, the display width WF of the file name is larger than the displayable area WD of the display 8, and the file If the name contains a specific character string (3-digit number string), leave the specific character string (3-digit number string), the beginning of the file name, and the extension part. Since the character string is displayed in the list in a display form in which other parts are omitted, even if a part of the character string constituting the file name is omitted, the user can individually select the character string based on the character string on the list. The data item can be identified with certainty.

  In the above-described embodiment, the predetermined symbol “!” Added to the beginning of the file name by the automatic file name assigning function is added at the end of the order relationship (sort order in ascending order) of all characters that can be used as the file name. Assumed as a defined predefined character. Therefore, the predetermined symbol “!” Can be said to be a symbol defined at the beginning of the order relation of all characters that can be used as file names in the descending sort order. That is, when the file group stored in the storage device 10 is sorted in descending order of the file name, the newly created file is always located at the top (or near the top) of the file group. In this case as well, the automatically assigned file name is clearly distinguished from other file name groups, so it is easy to find a newly created file, that is, a file with the name automatically assigned by the automatic assignment function. The effect that it is possible can be obtained.

  In the above embodiment, an example is shown in which the exclamation point symbol “!” Is assumed as the predetermined character defined at the end of the order relationship (sort order in ascending order) of all characters that can be used as file names. However, the characters defined at the end of the order relationship (sort order in ascending order) of all the characters that can be used as file names are added to the sort rule applied to the file system. Depending on. In addition, the character given to the head of the file name is not limited to the character defined at the end of the sort order in ascending order (hence, the head of the sort order in descending order), but the head of the sort order in ascending order (hence, The character defined at the end of the sort order in descending order may be adopted, and whether the character at the end or the beginning of the sort order in ascending order is adopted as the character given to the beginning of the file name. The user may be able to select arbitrarily.

In the above-described embodiment, the example in which the automatic file name assignment function operates when creating a new file has been described. However, the present invention is not limited to this, and a copy destination file is newly created by copying a file stored in the storage device 10. When the file name is created, the present invention is applied to the newly created copy destination file with a file name having “predetermined character (exclamation mark symbol“! ”In the above embodiment)” at the beginning. Can be granted automatically. Regarding the configuration of the file name automatically given in this case, some specific examples are given below.For example, if the file name of the copy source is `` abc002 '', the copy source file name `` abc002 '' has `` Newly created copy “! Abc003” with a predetermined character (exclamation mark symbol “!”) ”And the copy source file name with the last number“ 002 ”changed to a consecutive number. It can be used for the file name of the destination file. As another example, a “predetermined character (exclamation mark symbol“! ”)” Is added to the beginning of the copy source file name “abc002”, and a new “three-digit character” is added via a hyphen symbol at the end. The name “! Abc002-001” to which “numerical string” is added can be used as the file name of the newly created copy destination file. In any case, by placing “predetermined characters” at the beginning of the file name, the newly created file can be positioned at the end or the beginning of the sort order, and the file name of the copy source is the name of the new file. The relationship between the copy source and the copy destination can be identified by the file name.
In addition, when creating a new file (recording new data in a file) and copying an existing file, the predetermined character assigned to the beginning of the file name automatically assigned may be different. Good.

  In the above embodiment, when creating a new file, the case of automatically assigning a file name to the newly created file has been described. However, not limited to this, when creating a new folder, The present invention may be applied when a folder name is automatically given to the newly created folder.

  In addition, the object to which the file name is assigned by the automatic file name assigning function according to the present invention is not limited to the data file storing the MIDI performance data, but is a data file storing music data of other formats such as audio data. Also good. In addition, when creating a data file for storing some other data aggregate, not just music data, and a folder for storing the data file, the present invention is applied to automatically assign a file or folder name. You can also.

  In addition, although an example in which “three-digit number string” is detected as a specific character string portion in the file name in step S16 of FIG. 5 has been shown, the specific character string to be detected here is “3 Not only the “digit number string” but also a character string that can identify individual files can be adopted as appropriate. For example, a word having a specific meaning, an alphabet character string representing a MIDI sound source format suitable for reproduction of a music data file (for example, “GM” representing the GM standard, “XG” representing the XG standard, etc.), etc. It can be adopted as a “specific character string” to be detected. In addition, the user may be able to arbitrarily set a “specific character string”. In this case, the user may be able to specify an arbitrary character string or select a “specific character string” from a plurality of candidates. It may be possible. In the above embodiment, the “specific character string” to be detected is only one “three-digit number string”, but a plurality of “specific character strings” may be set as detection targets. .

  In the above embodiment, the rule for omitting a part of the character string constituting the file name is to leave the “first part”, “specific character string” part, and extension part of the file name, The other parts are omitted, but the rule for omitting a part of the character string constituting the file name may be a rule that leaves at least the “specific character string” part and omits the other parts. .

  Further, in step S18 in FIG. 5 described above, processing was performed so as to omit the display of the character string immediately before (to the left of) the specific character string (three-digit number string “001”). The extension is located after the 3-digit number string (right side), that is, the character string part that is left without omitting the character string after the 3-digit number string (right side) is located. Because it was. By the way, the position in the file name where a specific character string (“3-digit number string” in the above embodiment) to be left in the abbreviated display is inserted is not limited to immediately before the extension, but at the beginning of the file name. It may be located, or other character strings may be located both before and after a specific character string. Therefore, in such a case, in step S18 of FIG. 5, the display of the character string after the specific character string or both of the character strings before and after the specific character string is omitted.

  In the above embodiment, the file name list is a list for displaying a list of music data (MIDI performance data) files. However, the file name list is not limited to this and is a list of music data in other formats such as audio data. In addition to the music data, the accompaniment style data used for the automatic accompaniment function of the electronic musical instrument, the timbre data representing the timbre of the musical sound to be generated by the electronic musical instrument, the video data file for video playback, etc. If it is a list of some data items, the file name can be displayed in a form in which a part of the character string constituting the file name is omitted as necessary, as described above.

  Further, the electronic music apparatus to which the present invention is applied may be any type of electronic musical instrument known in the art as long as it has a mechanism for storing data files in a storage device. The present invention is applied not only to an electronic musical instrument that performs, but also to a music playback device that plays back audio files stored in a storage device, and an information processing device (such as a personal computer) that has a function of playing music or playing music. May be.
