Abstract

PURPOSE:To prevent the save and load of plural files whose contents are the same, and to discriminate the files whose contents are different by imparting a different identification number to the plural files recorded in a recording medium. CONSTITUTION:When the designated file is the newly prepared file or the edited(edit) file, the new file name is applied by a user, a 32 bit random number is generated, and the random number is written in a RAN 2 as the identification number of the designated file. Next, whether or not the same file name as the designated file name is present in an outside memory 1 is judged, and when this judgement is 'Yes', the user is allowed to select and execute the change of the file name, or the delete of the file of the same file name from the outside memory 1. Moreover, whether or not the desired entire files on the RAM 2 are saved is judged, and when this judgement is 'Yes', 'save completion' is displayed on a display circuit 6, and a series of processing is ended.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a floppy disk,
The present invention relates to a method of managing files recorded on a recording medium such as a hard disk and a magneto-optical disk.

[0002]

2. Description of the Related Art Conventionally, a plurality of files are saved in one recording medium with a set of data called a file as a unit. In this case, the file name is arbitrarily given by the user, and each file is usually identified by the file name.

[0003]

By the way, in the above-mentioned conventional file management method, since the files are identified by the file names, files having the same contents are separately saved in one recording medium if the file names are different. . Therefore, a plurality of files having the same content may exist in one recording medium. In such a case, the storage area of the recording medium is wasted, and the processing time for saving the files in the recording medium is wasted. There was a problem of using it for.

In addition, files are stored in RAM (Random Access).
When a plurality of files having the same content exist in one recording medium in the case of loading into a memory such as a memory), a plurality of files having the same content may be loaded together. In such a case, there arises a problem that the memory area is wasted and the processing time for loading the file into the memory is wasted.

Further, since the same file name cannot be managed in different recording media, files having the same file name with different contents may be saved. Here, when the files having the same file name cannot be loaded at the same time, there arises a problem that only one file can be loaded among a plurality of files having different contents.

The present invention has been made in view of the above-mentioned circumstances, and it is possible to eliminate useless processing at the time of loading or saving a file in an external recording medium, and efficiently use a recording medium or a memory such as a RAM. Therefore, it is an object of the present invention to provide a file management method capable of preventing a plurality of files having the same contents from being saved or loading and distinguishing files having the same file name with different contents.

[0007]

In order to solve the above-mentioned problems, the invention according to claim 1 generates different identification numbers inside a device for a plurality of files recorded in a recording medium. It is characterized by being automatically given.
The invention according to claim 2 is characterized in that, when a file is newly created or updated, a new identification number is generated inside the device and is automatically given to the file. Further, the invention according to claim 3 is characterized in that an identification number based on a random number is generated and automatically given to each of a plurality of files recorded on a recording medium.

[0008]

According to the present invention, a plurality of files having the same contents are saved because different identification numbers are generated inside the device and automatically given to the plurality of files recorded on the recording medium. In addition, it is possible to prevent the file from being loaded and to distinguish files having the same file name with different contents. As a result, useless processing at the time of loading or saving a file in the external recording medium can be eliminated, and the recording medium and the memory such as the RAM can be efficiently used.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the configuration of an electronic musical instrument to which the present invention is applied. In this figure, 1 is an external memory such as a floppy disk, a hard disk, a magneto-optical disk or the like. The external memory 1 stores files of wave data and voice data as shown in FIGS. These files all have different identification numbers (however, the same identification number is assigned to files with the same contents) and whether the files are wave data or voice data. The type name for identifying the type and the file name written by the user are recorded. Further, in the wave data file, environmental data regarding the sampling frequency, sound range and the like and waveform data based on PCM data are recorded. On the other hand, in the voice data file, in addition to the above-mentioned identification number, type name, and file name, various parameters such as pitch and volume, the identification number of the wave data file that is the combination data, and its file name. It is stored as tone color data.

As an example, the floppy disk A,
The data content of the file recorded in B is shown. The floppy disk A has files to which identification numbers (here, 100, 200, 300, and 400 for simplicity) are given. Voices, waves, waves, and voices are given as type names to these files, and analog synths, triangular waves, sawtooth waves, and synth brass are given as file names, respectively. Further, in the file with the identification number 100, the identification number of the file to be the combination data and the file name thereof are stored as “200 triangular wave + 300 sawtooth wave”, and various parameters are stored in addition to this. Similarly, in the file with the identification number 400, "30
“0 sawtooth wave + 300 sawtooth wave” and various parameters are stored. The combination data of the file with the identification number 400 is two wave data (“300
"Sawtooth wave + 300 sawtooth wave") is stored, but this is the same data for thickening the tone by delicately shifting the pitch by performing different processing on the two series of wave data. Is remembered.

On the other hand, on the floppy disk B, there is a file with an identification number 500. Identification number 50
To the file of 0, voice and synth brass are added as the type name and the file name, respectively, and the identification number of the file that is the combination data and the file name are stored like "300 sawtooth wave". In addition, various parameters are stored.

Reference numeral 2 in FIG. 1 is a RAM (Random Acces
s Memory), which has a work area of the CPU (central processing unit) 3 and a storage area for temporarily storing the file from the external memory 1 described above. Further, 4 is a ROM in which a control program is stored, 5 is a panel switch such as a keyboard, 6 is a display circuit for performing various displays to the user, and 7 is a tone generator circuit for generating a musical sound. CPU
3 is the above-mentioned external memory 1, RAM 2,
ROM 4, panel switch 5, display circuit 6, sound source circuit 7
To control.

Next, a processing procedure for the CPU 3 to load the file in the external memory 1 into the RAM 2 will be described with reference to FIG. First, when loading of a file is started by the CPU 3, the process proceeds to step S1 and the user specifies a file to be loaded. At this time, the designated file is designated by the identification number (ID) and the file name. Next, the process proceeds to step S2, and the file with the same identification number as the designated file is RA.
It is determined whether or not it exists in M2. This judgment is "Ye
In the case of "s", the process proceeds to step S3, the display circuit 6 displays "the specified file already exists",
A series of processing ends. That is, the same identification data means that the file contents are also the same, and therefore it is not necessary to newly load it.

When the determination in step S2 is "No", the process proceeds to step S4 and it is determined whether or not there is a file having the same file name as the file designated in step S1. If this determination is “Yes”, step S
5, the file name is changed by the user, and the process proceeds to step S6. In addition, the determination in step S4 is “No”
If so, step S6 is performed without performing step S5.
Go to. In step S6, the specified file is stored in RAM
2 and then to step S7. Step S
At 7, it is determined whether the type name of the loaded file is voice. If this determination is “No”, the process proceeds to step S8, the display circuit 6 displays “loading completed”, and the series of processes is completed.

If the determination in step S7 is "Yes", the flow advances to step S9 to determine whether or not there is a file having the same identification number as the identification number of the wave data file used in the voice data file. To judge. If this determination is “Yes”, the process proceeds to step S8, and if “No”, the process proceeds to step S10. In step S10, the wave data file to be used is RA
Load to M2.

In step S10, if the external memory 1 to be used is removable, such as a floppy disk, the wave data file to be used may exist on another floppy disk. In such a case, the currently inserted floppy disk is ejected, and the display circuit 6 indicates that another floppy disk should be inserted. When another floppy disk is inserted, the wave data file is searched. Such a process is repeated until the floppy disk containing the desired file is inserted. When this file is searched, this file is loaded into the RAM 2, the process of step S8 is performed, and the series of processes is completed.

Next, a processing procedure for the CPU 3 to save the file in the RAM 2 will be described with reference to FIG. In this example, all desired files on the RAM 2 are sequentially and automatically saved. First, CP
When the saving of the file is started by U3, the process proceeds to step S110, and any one of the files to be saved is automatically designated. At this time, if the specified file is a newly created file or an edited (edited) file, a new file name is given by the user, and the process proceeds to step S111. In step S111, it is determined whether the designated file is newly created or edited. If this determination is “Yes”, the process proceeds to step S112,
A 32-bit random number is generated, and the process proceeds to step S113. In step S113, a random number is written in the RAM 2 as an identification number of the designated file. Since a new identification number is given only to a newly created file or an edited file in this way, it can be said that files having different identification numbers necessarily have different file contents. In addition,
If the file is copied for some reason, the contents are the same and the identification data is also saved. Next, in step S114, it is determined whether the same file name as the specified file name exists in the external memory 1. If this determination is “Yes”, step S11
5, the user is made to select either to change the file name or to delete the file having the same file name from the external memory 1, and execute. When changing the file name, wait until the user changes the file name.
Next, when proceeding to step S116, the designated file is saved in the external memory 1, and then proceeding to step S117.
In step S117, it is determined whether or not all desired files on the RAM 2 have been saved. This judgment is "N
If “o”, the process returns to step S110, and “Yes” again.
If so, the process proceeds to step S118. In step S118, "save completed" is displayed on the display circuit 6, and the series of processes ends.

The determination in step S111 is "No".
In this case, the process proceeds to step S119, and it is determined whether the same identification number as the identification number of the designated file exists in the external memory 1. If this determination is “No”, the processing from step S114 is performed, and if “Yes”, the file does not need to be saved, so the processing in step S114 is performed.
Processing after 117 is performed.

The random numbers generated in the above step S112 rarely generate the same value as long as they are about 32 bits, but it is preferable to use an algorithm random number having a long cycle until the same one appears.

Next, the procedure for loading the files on the floppy disks A and B into the RAM 2 will be described with reference to FIG.
First, in step S1, the file "100
When "analog synth" is designated, the process proceeds to step S2.
Since there is no file with the same identification number as the identification number "100" of this file in RAM2,
The determination in step S2 is "No", and the process proceeds to step S4. In step S4, the file with the same file name as the file name "analog synth" of this file is RA.
Since it does not exist in M2, the result is "No" and step S6.
Go to. In step S6, the file "100 analog synth" is loaded, and the process proceeds to step S7. Since the loaded file "100 analog synth" is voice data, the process proceeds to step S9. Then, the combination data of this file are the files "200 triangular wave" and "3
Since it is "00 sawtooth wave", it is determined whether or not a file having the same identification number as the identification numbers of these two files exists in the RAM 2. The determination in step S9 is "N
Then, the files "200 triangular wave" and "300 sawtooth wave" are loaded into the RAM 2 in step S10. Next, the process proceeds to step S8, "loading completed" is displayed, and the series of processes ends.

Next, the process proceeds to step S1 again, and when the file "400 synth brass" is designated, the step S2 is performed as in the case of the file "100 analog synth" described above.
The processings 4, 6, 7, and 9 are sequentially performed. In step S9, the combination data of this file is the file “30
Since it is a "0 sawtooth wave", it is determined whether or not a file having the same identification number as the identification number of this file exists in the RAM 2. The determination in step S9 is "Yes", and the process proceeds to step S8. In step S8, "loading completed" is displayed, and a series of processing ends.

Next, the external memory 1 is replaced by the floppy disk A.
Replace with floppy disk B. Then, the process proceeds to step S1, and when the file “500 synth brass” is designated, the processes of steps S2 and 4 are sequentially performed as in the case of the file “400 synth brass” described above. In step S4, the file "400 Synth Brass" having the same file name exists in the RAM 2, so the determination here is "Yes" and the process proceeds to step S5. Step S5
Then, the file name of either of the files “400 synth brass” and “500 synth brass” is changed. In this case, the file name of the identification number "500" is changed to, for example, "Synth brass 1". The following processing is for file "4
"00 Synth Brass", steps S6, 7, 9, 8
Proceed to and the message "loading complete" is displayed, and the series of processes ends.

The method of assigning a random number as an identification number to a file of the present invention has the advantage that a common floppy can be used by an unspecified number of devices because it is not necessary to manage the assigned identification number. It is also possible to limit the number of devices to be used to one or to a plurality of specific devices, record the identification numbers that have already been used, and assign the new identification numbers other than the recorded identification numbers. If a limited number of devices are used, the identification number can be attached without using random numbers. In this case, the range of use is limited, but the file is managed more reliably than when a random number is used. Further, in this case, the newly added identification number may be the identification number of the deleted file. Although the file identification number is given when the file is saved in the external recording medium, it may be given when the file is created or when the file is changed. Further, although the voice data and the wave data are separated and the combined data of the wave data is held as the voice data, the wave data may be subordinate to the voice data and held. Further, although the present invention is applied to the electronic musical instrument, the present invention is not limited to this, and the present invention may be applied to other devices.

[0024]

As described above, according to the present invention, since a plurality of files recorded on a recording medium are provided with different identification numbers, a plurality of files having the same contents are saved. It is possible to prevent the file from being loaded and to load the file and to distinguish the files having the same file name with different contents. As a result, useless processing at the time of loading or saving a file in the external recording medium can be eliminated, and the recording medium and the memory such as the RAM can be efficiently used.
