Description

  The present invention relates to a method for saving a file on a computer.

Files that are managed in a shared manner, such as on a file server, may be edited after being copied to your computer for work. At that time, related files may be collected in the same folder for easy access.
However, related files may be stored in different folders with the same file name on the server, and when attempting to copy to the same folder, the user overwrites the file or changes the file name of either file Then you need to copy it.
At this time, if a file with the same name already exists in the copy destination folder, you can create a folder in the copy destination folder and save the file in that folder so that the file with the same name can be copied. There is a way to do it. (For example, refer to Patent Document 1.)

JP 2003-272345 A

However, in the prior art, since the process of creating a folder is performed by determining the duplication of the file name, the same file is not overwritten, and the file is stored in the folder.
Therefore, the present invention provides a method for determining identity using file attribute information, and determining whether to overwrite or rename and save.

  In order to solve the above-described problems, the present invention provides a document management system capable of moving or copying a file in a file system by means of additional information setting means for setting additional information for the file, and the additional information setting means. Additional information storage means for storing the set additional information, file movement means for moving or copying the file, and position information of the movement source file to be moved or copied by the file movement means in the additional information setting means When a file having the same file name as the file to be moved exists in the source information storage unit to be set and stored in the additional information storage unit and the destination folder to be moved or copied by the file moving unit Files with the same file name that exist in the destination folder Compare the source information of the additional information and the source information of the target file. If the source information of both files is the same, overwrite the file with the same file name in the target folder with the target file. If the source information of both files is different, the file name of the file to be moved is changed so that it does not overlap with the file in the destination folder, and a file duplication judgment means for moving or copying to the destination folder is provided. To do.

  According to the present invention, it is possible to determine whether a file is to be overwritten or renamed and saved on the basis of the place where the file was originally saved.

FIG. 10 is a diagram illustrating a hardware configuration of computers connected by a network according to a fourth embodiment.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram illustrating an example of a hardware configuration of an information processing apparatus according to an embodiment of the present invention.
In FIG. 1, a CPU 102 reads out and executes a control program such as an application program and OS stored in an external memory 109, temporarily stores information, files, and the like necessary for executing the program in a RAM 103, and performs control. It is a control means for performing.
A keyboard I / F 104 controls key input from a pointing device (not shown) such as a keyboard 105 or a mouse. The display I / F 106 controls display on the display 107. The external memory I / F 108 controls access to the external memory 109. The external memory 109 is connected to devices such as a hard disk (HD) and a floppy (registered trademark) disk (FD), and stores an application program and data files and setting files created by the application program.

FIG. 2 is a block diagram showing an example of the software configuration of the document management system according to the embodiment of the present invention. The document management system 200 is stored in the external memory 109 and is stored in the RAM 103 by the CPU 102 at the time of execution.
The document management system 200 includes a management target area control unit 202, a management target area operation unit 203, and an additional information control unit 204. The document management system 200 sets a partial area on the external memory as the management target area 201, and the management target area control unit 202 controls the files stored in the management target area (in the file system).

The management target area control unit 202 pairs the additional information created by the additional information control unit 204 (additional information setting unit) with respect to the file or folder stored in the management target area 201 in the management target area. Store (additional information storage means).
FIG. 3A shows the state of the file stored in the folder in the management target area and the file storing the additional information. In this example, A. txt and B.I. txt exists, but the additional attribute information of the file is the file name A.txt. txt. A file called “prop (B.txt.prop)” is stored in the same folder as the file to which additional information is to be attached.
Additional Information File A. txt. The storage format of the prop is shown in FIG. Here, the file A. As the additional information of txt, “movement source information”, “keyword”, and “comment” are added with the contents “C: ¥ ACB ¥ A.txt”, “text”, and “something”, respectively. By referring to this information, the user can easily organize the file or search for desired information.
Here, the storage location and format of the additional information shown are merely examples. For example, the setting information may be stored in a registry, or additional information of all files in the management area may be stored as a single file. Although the storage format has been described using XML in FIG. 3B, it may be stored as a TEXT file or an INI file.

  When accessing a file in the management target area, the user gives an instruction to the management target area operation unit 203 displayed on the display using a keyboard or a mouse. An example of the user interface of the management target area operation unit is shown in FIG. The management target area display unit 400 displays the folder structure in the management target area. The file list 401 displays a list of files stored in the folder selected by the management target area display unit 400. A file storing additional information is not displayed in the file list 401. Additional information of the file selected in the file list 401 is displayed on the additional information display unit 402.

  The user can use the management target area operation unit 203 to instruct the file / folder in the management target area to change the name, delete, move, copy, set additional information, and the like. Upon receiving an instruction from the user, the management target area operation unit 203 transmits the instruction to the management target area control unit 202 and controls the files in the management target area.

Processing when file duplication occurs due to file operations in the management area of this embodiment will be described with reference to the flowchart of FIG. Note that the document management system that executes the processing of this flowchart is stored in the external memory 109, read into the RAM 103 at the time of execution, and processed by the CPU 102. The file is stored in the external memory 109 and is read out to the RAM 103 when an operation is performed on the file. When the processing is completed, the contents changed according to the processing are written into the external memory 109.
This flow is executed when the user gives an instruction to move from the original location of the file, such as moving or copying the file, to another location. As an example of the user operation at that time, there is a method of dropping a file on the management target area display unit 400 or the file list 401 of FIG. 4 by a mouse drag and drop operation. There is also a method of moving the file selected on the file selection screen of FIG. 6 to the folder being selected in the management target area display unit 400.
In the present embodiment, processing for moving from the original location of the file, such as file movement / copying, which is instructed by the user, to another location is collectively defined as “file movement processing”.

  When a file movement process is instructed by the user to the management target area operation unit 203, additional information of the movement target file is created, and the position information of the movement source of the file is stored as movement source information (movement source information storage means) , S500). Note that the storage location of the transfer source file may be within the management target area, or may be stored in other locations. At this time, the created additional information is stored only in the RAM 103 at this stage, and is stored in the external memory 109 when the file movement processing is completed. The location information of the file move source is created and stored during the file move process from the user. For example, on the file selection screen in FIG. 6, the path of the file selected by the user is stored as the source information.

  Next, it is checked whether a file having the same file name as the file to be moved exists in the destination folder (S501). If a file having the same file name does not exist in the destination folder, the target file can be stored with the same file name, so that the file name is not changed and stored in the destination folder (S502). When a file having the same file name exists in the destination folder, the source information of the additional information of the file and the target file is compared (S503). If the movement source information of both files is different, the file name to be moved is changed to a file name that does not exist in the movement destination folder and stored (S504). If the movement source information of both files is the same, it is assumed that they are originally the same file, and the file in the movement destination folder is overwritten with the movement target file (S505).

  As a simple example of the method of changing the file name in S504, there is a method of incrementing the number by 1 in order from 1 at the end of the original file name (before the extension). For example, A.I. In the case of txt, A1. Let it be txt. A1. If txt exists in the destination folder, A2. Let it be txt.

A more complicated example of the file name change process in S504 will be described with reference to the flowchart of FIG. In this method, the path of the transfer target file is compared with the path of the transfer destination folder, and a different part is added to the end of the original file name (before the extension).
First, the destination folder path is decomposed for each folder, and each folder name is stored in the RAM 103 (movement destination folder path decomposition means, S700). For example, if the destination folder path is “C: ¥ January ¥ Budget”, it is decomposed into “C:”, “January”, and “Budget”. Similarly, the file path of the movement target file is also decomposed for each folder (movement target file path decomposition means, S701). For example, if the file path of the transfer target file is “C: ¥ February ¥ Budget ¥ A.txt”, the file is decomposed into “C:”, “February”, and “budget”. The file name is not used because it is the same. Then, the folder name extracted in S700 is compared with the folder name extracted in S701, and the folder name extracted from the migration target file and having the same name is extracted (folder path comparing means, S702). When the example used in the description of S700 and S701 is used, “February” is extracted as a difference. The extracted character string is added to the end of the original file name (S703), and the file name is stored in the destination folder (S704). For example, if the original file name is A. If it is txt and the difference extracted in S702 is “February”, then A2. It is stored with the file name txt. If there are a plurality of folder names extracted as differences, a plurality of folder names are connected. For example, if the original file name is A. txt, and if the extracted difference is “February” and “Budget”, then A February Budget. It is stored with the file name txt. In addition, when there are a plurality of folder names extracted as differences, any one of the differences may be used without connection. An arbitrary delimiter is inserted between the original file name and the added difference character string, and A_February. You may make it like txt.

  By the above procedure, if a file with the same file name exists in the destination folder, determine the identity of the file and determine whether to overwrite or rename the file (file duplication determination). Can do.

  In the first embodiment, only the source information is used for determining whether to overwrite or change the file name and save, but it is also possible to determine using information such as the file size and update date. It is also possible to switch overwriting and file name change operations by combining these conditions.

FIG. 8 shows an example of a user interface for setting which method is used as the determination for overwriting a file. By performing this setting before instructing the file movement process, the user stores the setting information of the application program in the RAM 103, refers to the setting in the movement process, and switches the operation.
As an example of settings to be used, a method for determining whether or not the source information used in the description of the first embodiment is the same, a method for determining whether or not the file sizes are the same, and the update date and time of a file existing in the destination folder There is a method of judging whether it is older than the update date of the file to be moved. Whether or not to use each determination method can be set using a check box. The checked method is used to determine whether to switch the operation of overwriting or changing the file name in the file move process. The file movement process when the operation switching process is added will be described with reference to the flowchart of FIG.

The processing from S900 to S902 is the same as S500 to S502 in FIG.
If it is determined in S901 that there is a file having the same file name in the transfer destination folder, it is determined whether or not the transfer source information is used for determination to overwrite the file (S903). If there is a check for checking whether the source information is the same in the setting of FIG. 8, the source information is compared (S904), and if there is no check, the process proceeds to S906. Since S904 is the same process as S503 in FIG. If the migration source information is not the same, it is determined that the same name file existing in the migration target file and the migration destination folder are different, and the migration target file is stored with the file name changed (S905). The file name change process uses the same process as in the first embodiment. If the source information is the same, the process proceeds to S906.

  In S906, it is determined whether or not the file size is used for determining whether to overwrite the file. If there is a check for checking whether the file sizes are the same in the setting of FIG. 8, the file sizes are compared (S907), and if there is no check, the process proceeds to S908. In S907, the file size of the file to be moved is compared with the file size of the file of the same name stored in the destination folder. If the file sizes are different, it is determined that the file with the same name existing in the transfer target file and the transfer destination folder are different, and the file to be moved is renamed and stored (S905). The file name change process uses the same process as in the first embodiment. If the file sizes are the same, the process proceeds to S908.

  In step S908, it is determined whether or not the file update date is used for determining whether to overwrite the file. If there is a check for checking whether or not the update date and time of the same name file existing in the destination folder is old in the setting of FIG. 8, the update date and time are compared (S909), and if there is no check, the process proceeds to S910. If the update date and time of the file with the same name existing in the migration destination folder is older than the update date and time of the migration target file in S909, the file in the migration destination folder is overwritten with the migration target file (S910). If the update date of the file in the destination folder is not old, the file to be moved is renamed and stored (S905). The file name change process uses the same process as in the first embodiment.

In this way, when the determination in S903, S904, S906 to S909 is performed and it is determined that they are the same file, the files are originally regarded as the same file, and the file stored in the transfer destination folder is overwritten with the transfer target file. (S910).
According to the above procedure, when a file having the same file name exists in the migration destination folder, it is possible to determine the identity of the file and determine whether to overwrite or change the name and save.

  In the present embodiment, the source information of the additional information, the file size, and the update date / time are used as the means for determining the identity of the file. Judgment can also be made.

  In the first embodiment, a process for changing the file name of the transfer target file and storing it in the transfer destination folder is performed. However, the file name of the same name file in the destination folder can be changed instead of the file name of the movement target file, and the file name of the movement target file can be stored as it is. A file move process when performing the process will be described with reference to the flowchart of FIG. Note that the document management system that executes the processing of this flowchart is stored in the external memory 109, read into the RAM 103 at the time of execution, and processed by the CPU 102. The file is stored in the external memory 109 and is read out to the RAM 103 when an operation is performed on the file. When the processing is completed, the contents changed according to the processing are written into the external memory 109.

  The processing from S1000 to S1003 and S1006 is the same as S500 to S503 and S505 in FIG. Therefore, the difference from the process of FIG. 5 is only the process when a file having the same file name as the file name of the migration target file exists in the migration destination folder and the migration source information of the additional information of both files is different. . Therefore, the part will be described.

  When a file having the same file name as the file to be moved exists in the movement destination folder and the movement source information of the additional information of both files is different (S1003, NO), the same file name existing in the movement destination folder The file name of the file is changed (S1004). The file name change process uses the same process as in the first embodiment. Since the file name on the destination folder side is changed, there is no file having the same file name as that of the file to be moved. Therefore, the migration target file can be stored in the migration destination folder without changing the file name (S1005).

  According to the above procedure, when a file having the same file name exists in the destination folder, it is possible to determine the identity of the file and determine whether to overwrite or rename and save.

  In the first embodiment, the management target area is arranged in the external memory in the same PC as the document management system, but the area of the external memory shared in the PC connected via the network is used as the management target area. You can also. The hardware configuration in that case is shown in FIG. In the hardware configuration of the client PC, the same parts as those shown in FIG. 1 have the same functions, so only different parts will be described.

In FIG. 11, the client PC includes a network I / F 1100 and controls network access from the outside. Access to a file stored in the external memory 1102 in the server PC through the network can be performed by using a protocol such as SMB (Server Message Block).
The processing described in the first to third embodiments can be realized regardless of whether the file to be moved and the folder to be moved exist in either the client PC or the server PC.

(Other examples)
The present invention can also be realized by executing the following processing. That is, software (program) that realizes the functions of the above-described embodiments is supplied to a system or apparatus via a network or various storage media, and a computer (or CPU, MPU, or the like) of the system or apparatus reads the program. It is a process to be executed.
