BACKGROUND OF THE INVENTION
The present invention relates to a file management program, a computer-readable recording medium that records the file management program, and a file management method, and more particularly, a file management program that virtually combines a plurality of files, and a computer-readable recording medium that records the file management program. The present invention relates to a possible recording medium and a file management method.
[0002]
[Prior art]
Conventionally, in a personal computer or the like, a file is recorded in a hard disk. When the number of files to be recorded becomes too large, it becomes difficult for the user to find a desired file from file names including file names or folder names. In particular, a file created by a different application, for example, an image file representing image data or a document file created by a word processor application cannot be made into one file because the file formats are different. However, since there is a connection between a travel photo image file and a document file that describes the content of the trip, or a project document file and an image file that shows graphs or pictures, it can be handled as a single file. Is desirable. For this reason, although the files recorded on the hard disk are different, there is known a virtual joining technique for virtually joining a plurality of files as if they were one file.
[0003]
When a plurality of files are virtually combined, the user can handle them as one file without being conscious of the fact that the plurality of files are different files. When visually confirming the contents of a plurality of virtually combined files, the plurality of virtually combined files are sequentially displayed as thumbnails obtained by reducing the files. By turning the page, thumbnails of a plurality of virtually combined files are sequentially displayed. In addition, by inputting an instruction for designating a file by, for example, double-clicking the mouse on a desired page, an application corresponding to the designated file is activated, and the file is read and can be edited.
[0004]
For this reason, when a plurality of files are virtually combined, the contents of the files can be confirmed and edited without performing a predetermined operation on each of the plurality of files, and the handling becomes easy.
[0005]
[Problems to be solved by the invention]
However, when releasing one file from a plurality of virtually combined files, the virtual combination of the plurality of files must be canceled. Also. There is no information that the file released from the virtual join was previously virtual joined. Furthermore, the virtual join must be performed again on the files other than the files released from the virtual join, and the processing is complicated.
[0006]
For this reason, when multiple files are virtually joined, or when some files are removed from the virtually joined file, whether or not these files are virtually joined by the user It was annoying because we had to figure out.
[0007]
In addition, since the file released from the virtual join has no relationship with other files, in order to make a virtual join with another file again, the virtual join process must be performed again before the release by a simple operation. Could not be restored to its original state.
[0008]
The present invention has been made to solve the above-described problems, a file management program capable of easily managing a plurality of associated files, a computer-readable recording medium recording the file management program, and Its purpose is to provide a file management method.
[0009]
[Means for Solving the Problems]
In order to achieve the above object, according to one aspect of the present invention, a file management program stores information indicating a relationship between a plurality of files and information indicating a relationship between the plurality of files. Identifying the selected file as a deletion target while maintaining the information indicating the relationship between each of the plurality of files, combining the plurality of files into one file, selecting at least one of the plurality of files And causing the computer to execute
[0010]
Preferably, the file management program moves the file identified as the object to be deleted to a specific folder, accepts an instruction to restore the file in the specific folder, and restores the file that received the restore instruction to the original Restoring to the combination of files.
[0011]
Preferably, the file management program further includes a step of combining the files existing in the specific folder based on information indicating the relationship between each of the plurality of files.
[0012]
Preferably, the file management program deletes the file identified as the object to be deleted from the storage device at a time point designated by the user or at the end of the file management program, and information indicating a relation between each of the plurality of files And deleting the information on the deleted file and correcting the information of the other file combined with the deleted file.
[0013]
According to another aspect of the present invention, a computer-readable recording medium records any one of the file management programs described above.
[0014]
According to still another aspect of the present invention, a file management method stores a plurality of files on the basis of a step of holding information indicating a relationship between each of a plurality of files, and information indicating a relationship between each of the plurality of files. Combining at least one file, selecting at least one of the plurality of files, and identifying the selected file as an object to be deleted while maintaining information indicating a relationship between each of the plurality of files. .
[0015]
According to these inventions, it is possible to identify a selected file as a deletion target while retaining information indicating the relationship between each of a plurality of files, and thus it is possible to easily manage a plurality of associated files. File management program, a computer-readable recording medium recording the file management program, and a file management method can be provided.

[0018]
The control unit 101 stores a central processing unit (CPU), a read-only memory (ROM) for storing a program to be executed by the CPU, and variables necessary for executing the program by the CPU. Includes random access memory (RAM).
[0019]
The input unit 105 is a keyboard or a mouse, and can input characters or numbers or a predetermined instruction command.
[0020]
The storage unit 103 stores data such as characters or images. These data are, for example, data files created by word processor application programs, data files created by spreadsheet software applications, data files consisting of images read by digital cameras or image scanners, or other Data files created by various application programs.
[0021]
The storage unit 103 has a plurality of folders, and can classify the folders and store the data files. For example, a data file created by a word processor may be stored in a certain folder A, and a data file created by spreadsheet application software may be stored in another folder B. Furthermore, a folder may be created for each predetermined case, or a folder may be created with a predetermined period divided based on the date on which the data file was created. These folders are created from known application programs.
[0022]
The output unit 107 is a display such as a liquid crystal display device, and displays information related to the data file in accordance with instructions from the control unit 101. The information regarding the data file includes the file name of the data file, the file size, the date of creation or update, the thumbnail for displaying the data file in a reduced size, and the like. When the display instruction from the control unit 101 is a thumbnail, thumbnails of a plurality of data files are simultaneously displayed in one window.
[0023]
The external storage device 109 reads a program or data recorded on a computer-readable recording medium 111 and transmits it to the control unit 101. Further, in accordance with an instruction from the control unit 101, necessary data is written in the computer-readable recording medium 111.
[0024]
The computer-readable recording medium 111 is a tape system such as a magnetic tape or a cassette tape, a disk system such as a magnetic disk (flexible disk, hard disk device, etc.) or an optical disk (CD-ROM / MO / MD / DVD, etc.), or an IC card. It is a medium that carries a fixed program such as a card system (including a memory card) or an optical card, or a semiconductor memory such as a mask ROM, EPROM, or flash memory. Further, the recording medium 111 may be a medium that fluidly carries the program so that the program is downloaded from the network.
[0025]
The control unit 101 can execute the read program by reading the file management program recorded on the recording medium 111 with the external storage device 109.
[0026]
FIG. 2 is a diagram schematically illustrating the configuration of a file stored in the storage unit 103 of the file management apparatus 100 according to the present embodiment. Referring to FIG. 2, in file management apparatus 100, a plurality of files are stored in storage unit 103, and file management software 200 is executed by control unit 101. FIG. 2 shows a state where a plurality of files to be managed by the file management software 200 are stored in the storage unit 103. Hereinafter, a file to be managed by the file management software 200 is referred to as a management target file. Here, the management target files stored in the storage unit 103 are shown as a file whose file name is “File-1”, a file whose file name is “File-2”, and a file whose file name is “File-n”. ing.
[0027]
The file management software 200 is executed by the control unit 101 to create a management information file for associating management target files and handling them as one file. The created management information file is stored in the storage unit 103. The management information file may be stored in the file management software, or the management information file may be stored separately from the file management software.
[0028]
The management information file includes data consisting of items of file name and assignment information. The management information file is data in which the assigned information is associated with the file names of File-1 to Filen, which are management target files. The file name is unique information for identifying the file.
[0029]
FIG. 3 is a diagram illustrating an example of a management information file created by the file management apparatus 100 according to the present embodiment. Referring to FIG. 3, the management information file includes data of a file name item, an item indicating whether or not to delete, and a combination destination item. The item to be deleted is an item for specifying whether or not the file is to be deleted. If the item is to be deleted, the item is marked with “◯”. FIG. 3 shows that FILE-1 to n are not to be deleted.
[0030]
Files marked with “◯” in the items to be deleted indicate that they are to be deleted. The file to be deleted is stored in a specific folder.
[0031]
The file name item indicates the file name of the management target file. The combination destination item indicates the file name of the file having the rank immediately before the file specified by the file name item.
[0032]
Further, the order of the management target files is determined by the item of the combination destination. Note that the order of all files to be managed in the management information file may be determined, but the order of only the virtually combined files may be determined. Here, a case will be described as an example where the order is determined for all the files to be managed.
[0033]
Referring to FIG. 3, the file with the file name “File-2” has a blank destination item and indicates that the rank is the highest among the management target files. For the file with the file name “File-1”, the file name “File-2” is associated with the item to be combined. This indicates that the file with the file name “File-1” has the next order of the file with the file name “File-2”. Similarly, for the file with the file name “File-3”, the file name “File-1” is associated with the item to be combined. Therefore, the file “File-3” indicates the next order of the file whose file name is “File-1”. Therefore, the order of the files is determined in the order of the file having the file name “File-2”, the file “File-1”, and the file “File-3”.
[0034]
The file management apparatus according to the present embodiment has a management information file for each folder, and searches for a folder having the management information file when the file management program is started. As a result, a file stored in the external storage device 109 that can be temporarily connected to or disconnected from the file management device 100 can be included in the management target regardless of whether or not the external storage device 109 is connected. That is, the external storage device 109 can be a management target when connected to the file management device 100, and is not a management target when disconnected.
[0035]
Further, even when a file managed by another file management apparatus is stored in the storage unit 103 for each folder via a recording medium such as a flexible disk, a network, or a removable drive, the file is stored in the folder. Data files that have been processed can be immediately included in the management target.
[0036]
Furthermore, a portable terminal equipped with a storage device, a scanner, a multifunction device combining a scanner and a printer, or a copier capable of receiving and printing data from a personal computer can be connected to the file management device 100. For example, data files in those storage devices can be managed.
[0037]
FIG. 4 is a flowchart showing a flow of management information file creation processing performed by the file management apparatus 100 according to the present embodiment. Referring to FIG. 4, in the file management apparatus 100, first, the user uses the input unit 105 to select a file to be virtually combined from among a plurality of files stored in the storage unit 103 as a management target file. In addition, a virtual join instruction is input by designating the order of the selected management target files (step S1).
[0038]
More specifically, the file name of the file stored in the storage unit 103 is displayed on the display of the output unit 107 of the file management apparatus 100. The file displayed on the display may be a file classified into one folder or all of the files classified into a plurality of folders. The user selects the file name of the file to be virtually combined from the file names displayed on the display of the output unit 107 using the mouse of the input unit 105 or the like. As a result, the selected file is selected as a management target file. In addition, the order of the management target files is determined in the order of selection. Instead of determining the order of the files to be managed in the order of selection, the file names or thumbnails of the selected files are displayed in the order of selection in another window and displayed using the input unit 105 such as a mouse. The order of the files may be changed by changing the file name or the arrangement order of the thumbnails in the thumbnail window.
[0039]
Then, the file name of the selected management target file is assigned to the file name item of the management information file, and the file name of the immediately preceding file is assigned to the merged item of the management information file according to the specified order ( Step S2). In FIG. 3, since the file immediately before File-1 is File-2, the file name “File-2” is assigned to the item to be combined in File-1. Since File-2 has the highest rank, there is no previous file. In this case, a blank is assigned to the item to be combined in File-2. Furthermore, since the file immediately before File-3 is File-1, “File-1” is assigned to the item to be combined in File-3.
[0040]
In this embodiment, in order to assign the order of files, the immediately preceding file name is assigned to the item to be combined. However, the present invention is not limited to this, and the file name of the immediately following file is assigned. May be assigned. In addition, two file names, the file name of the immediately preceding file and the file name of the immediately following file, may be assigned to the items to be combined. By doing in this way, the processing speed in partial cancellation | release of the virtual coupling | bonding mentioned later and recombining can be accelerated.
[0041]
Furthermore, when the size of the management information file is not limited, the file names of all the files that precede the file and their ranks, or the names of all files that follow the file The file names and their order may be assigned to the items to be combined.
[0042]
Then, it is determined whether or not the file name of the immediately preceding file has been assigned to the combination destination item for all of the management target files (step S3). If the allocation is not completed, the process proceeds to step S2, and the process of step S2 is repeated until the process is completed for all managed files.
[0043]
FIG. 5 is a diagram showing an example of a file display window displayed on the display in the detailed display process performed by the file management apparatus according to the present embodiment. Referring to FIG. 5, two thumbnails 301 and 302 are displayed on screen 300 displayed on the display. Here, the thumbnail 301 consists of a single file, and the thumbnail 302 shows a state (virtual file) in which three files are virtually combined. When the mouse pointer 310 is placed on the thumbnail 302, a file display window 303 is displayed.
[0044]
The file display window 303 displays the file names of the three files. Here, the three file names are “cow.jpg”, “report1.doc”, and “report2.txt”. Therefore, the thumbnail 302 displays an image obtained by reducing any one of the three files.
[0045]
FIG. 6 is a diagram showing an example of an operation list window displayed on the display in the detailed display process performed by the file management apparatus according to the present embodiment. Referring to FIG. 6, thumbnail 301, thumbnail 302, and file display window 303 are displayed on screen 300 displayed on display 107. When the mouse pointer 310 is moved to any file name in the file display window 303, an operation list window 304 is displayed. In the figure, the mouse pointer 310 is set to the file name “report1.doc”.
[0046]
In the operation list window 304, operation items "Open", "Delete", and "Copy" are displayed. “Open” is an item indicating an operation of processing for starting the application program corresponding to the file and opening the file. “Delete” is an item indicating an operation of a process for deleting a file (Delete), and “Copy” is an item indicating an operation of a process for copying a file (Copy). In addition to these operation items, items such as an operation item for printing a file and an item for changing the name of the file may be added. May be displayed in the operation list window.
[0047]
On the screen shown in FIG. 6, the mouse pointer 310 is moved to one of the operation items displayed in the operation list window 304 and double-clicked to operate the file specified in the file display window 303. The operation specified in the list window 304 is executed. For example, when the mouse pointer is moved to “Delete” in the operation list window 304 after the mouse pointer is moved to “report1.doc” in the file display window 303, the file whose file name is “report1.doc” Will be deleted.
[0048]
As described above, in the file management apparatus according to the present embodiment, when a plurality of virtually combined files are displayed as one thumbnail, when the pointer of the pointing device is aligned with the thumbnail, A file display window for displaying the file name of the virtually combined file is displayed. Therefore, it is possible to know the virtually combined file by the file name without page-turning the thumbnail 302.
[0049]
Further, the operation list window 304 is displayed when the mouse pointer points to one of the file names displayed in the file display window 303. Then, the operation with the mouse pointer in the operation list window 304 is performed on the file with the mouse pointer in the file display window 303. Therefore, it is possible to perform a predetermined operation on each file without canceling the virtual combination of the plurality of virtually combined files.
[0050]
FIG. 7 is a flowchart showing the flow of the virtual join partial release (deletion) process performed by the file management apparatus 100 according to the present embodiment. Referring to FIG. 7, in the virtual link partial release process, first, a virtual file is designated by the user (step S11). More specifically, when the contents of a folder are displayed on the display of the output unit 107 in the file management apparatus 100, a virtual combined thumbnail is displayed for the virtual files classified in the folder. By specifying the virtual combination thumbnail displayed by the user using the mouse of the input unit 105 or the like, a virtual file (a set of virtually combined files) is specified.
[0051]
When the virtual file is designated, the management information file specified by the virtual combination thumbnail is read from the storage unit 103, and the combination destination data is selected from the data included in the management information file. Data of the item of the file name is displayed on the display of the output unit 107 (step S12, state of FIG. 5). Instead of the file name or together with the file name, a thumbnail of the file specified by the selected data may be displayed.
[0052]
From the displayed files that are virtually combined, a file that the user desires to cancel (delete) the virtual combination is designated (step S13). Here, in order to simplify the description, the file from which the virtual connection is released is referred to as file A. Then, among the data of the management information file, “◯” is assigned to the item to be deleted of the data specified by the file A (step S14). Further, the file A is moved to a specific folder (for example, a “trash box” folder).
[0053]
As described above, the file corresponding to the data can be deleted from the virtual combination only by rewriting the item to be deleted of the data included in the management information folder created by performing the virtual combination process.
[0054]
When the document management software program ends, when the apparatus is turned off, or when the user designates a time (such as when a command such as “Empty Recycle Bin” is input) (step S15). YES), the file A moved to the specific folder is completely deleted from the storage unit 103 (step S16). Thereafter, the information of the file A is deleted from the management information file (step S17), and the item to which the management information file is combined is corrected, thereby creating a virtual combined file excluding the file A (step S18).
[0055]
FIG. 8 is a diagram showing a state in which the user has deleted File-1 from the state of FIG. Referring to the figure, File-1 is moved to a specific folder (a folder for temporarily storing a file) in which a file to be deleted is stored. Then, “◯” is added to the item to be deleted of File-1 of the management information file. However, the other information of File-1 is not changed, and the information of the combination destination is left without being deleted.
[0056]
In this way, by leaving information relating to the connection to the file to be deleted, it becomes easy to restore the file to be deleted to the original virtual connection.
[0057]
That is, since the connection destination information of the management information file is stored without being deleted, when File-1 is deleted, File-3 uses the connection destination instead of File-1 that was previously in the virtual connection. By tracing, the previous File-2 is detected and combined after File-2. In addition, restoring File-1 to the original virtual combination is easily realized because the combination destination information remains.
[0058]
FIG. 9 is a diagram showing a state when there are a plurality of files to be deleted. In this figure, the original virtual combination is combined in the order of File-2, File-1, File-3, and File-4. Of these, File-1 and File-4 are to be deleted. It is going to be.
[0059]
FIG. 10 is a diagram showing a screen displayed on the display when the user restores File-1 from the state of FIG. Referring to the figure, a thumbnail of File-1 and a thumbnail of File-2 are displayed on the screen.
[0060]
When the mouse pointer is placed on the thumbnail of File-1, a window 351 is displayed. When the user designates the item “restore” in the window 351 and double-clicks, the file is restored to the virtual combination.
[0061]
In this embodiment, if one file that is to be deleted is specified to be restored, other deletions that have been combined with the original virtual combination from the combination destination information and deletion target information of the management information file The target file is extracted and restored to the virtual connection. More specifically, in the example of FIG. 9, if it is specified that File-1 is to be restored, this file is first restored to the original virtual combination. At this time, if the connection destination information of the management information file is followed, the existence of File-4 is determined. Moreover, since File-4 is a deletion target, File-4 is also restored to the virtual combination.
[0062]
In this embodiment, when one file is selected, all files that can be restored to the virtual combination are restored. However, a user may add a condition desired by the user to the restored file. For example, a file that is newer than a certain point in time is restored, or only files that have a file size smaller than a certain value are restored. Of course, the user can restore only one specified file.
[0063]
FIG. 11 is a flowchart illustrating a process for returning a file in a folder in which a deletion target file is stored to a virtual combination. Here, a file designated for restoration is called a “designated file”.
[0064]
In step S101, “◯” of the item to be deleted of the designated file is deleted from the management information file. Next, the file specified in step S103 is returned to the original virtual combination (from the folder in which the file to be deleted is stored to the original position).
[0065]
In step S105, the link destination information is traced on the management information file. In step S107, it is determined whether or not there is a file to be deleted. If YES, the deletion target item “◯” in the corresponding file is deleted in step S109. In step S111, the corresponding file is restored to the original virtual combination, and the process returns to step S105.
[0066]
Note that if the answer is NO in step S107, this routine ends.
It should be noted that, in the folder in which the files to be deleted are stored, the files that have been joined to the original virtual join can be joined together to form a new virtual join that is different from the original virtual join.
[0067]
In the example of FIG. 12, File-1 and File-4 are to be deleted, but it is found that both files were in the same virtual combination by following the combination destination information on the management information file. . Here, a new virtual connection can be configured in the order of File-1 and File-4.
[0068]
In this way, if the files to be deleted are configured as another virtual join in the sense that they are grouped in relation to the original virtual join, when the user restores the file, the related file can be easily grasped and restored. File selection is also simplified.
[0069]
In the above embodiment, it is shown that the file is handled from the viewpoint of the deletion target. However, a specific definition defined by the user and a file matching this definition are temporarily stored in a specific folder defined by the user. You may make it store in. Further, the above-described embodiment can also be applied to a case where a plurality of files selected in the virtual combination deviate from the virtual combination and constitute another virtual combination.
[0070]
As described above, according to the present embodiment, in the document file management system, a plurality of files to be deleted are restored to the original virtual combination by leaving the combination destination information of the virtual combination and recording the deletion target. Or a virtual join can be configured with only files to be deleted. As a result, it is possible to facilitate temporary deletion and restoration of some files of the virtual combination.
[0071]
The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
