DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a file distribution system, and more particularly to a file distribution system in a file system for storing files in a directory having a hierarchical structure on a storage medium such as a hard disk or floppy disk.

[0002]

2. Description of the Related Art Operates on a personal computer,
For example, operating systems such as MS-DOS and WINDOWS (both are registered trademarks of Microsoft Corporation) manage files by a file system in a directory having a hierarchical structure on a storage medium such as a hard disk and a floppy disk.

In such a file system, conventionally, when a file is newly created using an application program, when saving the newly created file, a directory for saving the file has a hierarchical structure. Either specify the absolute path name to the directory to describe all, or use the file manager to search and select the directory to save the file with the mouse or keyboard operation.

[0004]

In the above-mentioned conventional file system, since it is necessary to use an absolute path name to specify the directory for storing the created file, the user needs to write the hard disk, floppy disk, or the like. It is necessary to grasp all the hierarchical structure of directories on the storage medium, and there is a problem that an error occurs if the designation is made by incorrect recognition.

Further, even in the method of searching and selecting the designation of the directory in which the file is saved by operating the mouse or the keyboard, the work of searching the absolute path of the directory in which the file is saved first occurs, so the user There is a problem in that it takes time to search and select a directory for saving a file unless the directory structure of the storage medium is recognized.

In view of the above points, an object of the present invention is to register in advance a set of a directory identifier and an absolute path name to the directory in the file allocation table, and the directory identifier included in the file name is used for the file allocation table. It is to provide a file distribution method in which files are automatically distributed to directories with absolute path names corresponding to the directory identifiers registered in.

[0007]

According to the file allocation method of the present invention, in a file system for storing files in a directory having a hierarchical structure on a storage medium, a file allocation table includes a directory identifier corresponding to the directory, A distribution table registration means for registering a combination with an absolute path name to a directory and file names of all files existing on the storage medium are acquired,
If the directory identifier included in the file name matches the directory identifier registered in the file allocation table, the file with a new file name excluding the directory identifier is added to the directory of the corresponding absolute path name. And a file sorting means for moving the file.

[0008]

In the file distribution method of the present invention, the distribution table registration means registers a set of a directory identifier corresponding to a directory and an absolute path name to the directory in the file distribution table, and the file distribution means stores on the storage medium. If the directory identifiers included in the file names of all the files that exist in the file name match with the directory identifiers registered in the file distribution table, the directory with the corresponding absolute path name is created without the directory identifier. File name
In moving the file.

[0009]

Next, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of a file distribution system according to an embodiment of the present invention. The file distribution method of this embodiment is composed of a distribution table registration means 1, a file distribution means 2 and a file distribution table 3 as its main components. Note that reference numeral 4 indicates a pre-execution file system, and reference numeral 5 indicates a post-execution file system.

Referring to FIG. 2, the process of the distribution table registration means 1 is a registration screen display step S101,
It includes a directory identifier and absolute path name input step S102 to the directory, an input error / input omission check step S103, and a file allocation table registration step S104.

Referring to FIG. 3, the processing of the file allocating means 2 is performed by a file allocating table search step S201, a registration information presence / absence determining step S202, a search key setting step S203, a file name acquisition step S204, and a search key. / Directory identifier match determination step S205 and file move step S206
And a file name presence / absence determining step S207 and a directory identifier presence / absence determining step S208.

Next, the operation of the file distribution system of this embodiment having the above-mentioned configuration will be described.

Since the file allocation table 3 is referred to by the file allocation means 2, it needs to be registered in advance. Therefore, the user first activates the distribution table registration means 1 to register an arbitrary set in the file distribution table 3 as a set of a directory identifier and an absolute path name to the directory.

More specifically, the distribution table registration means 1
Displays a registration screen (step S101), and inputs a pair of a two-character directory identifier and an absolute path name to the directory on the registration screen (step S102).

Next, the user confirms whether or not there is an input error or omission (step S103), and if there is, an input step S103.
The control is returned to 102, and steps S102 and S10 are performed.
Repeat 3.

When a desired number of sets of directory identifiers and absolute path names to directories are input, the distribution table registration means 1 is instructed by the user to cause the distribution table registration means 1 to input the directory identifiers and absolute paths to directories. All pairs with the name are registered in the file allocation table 3 (step S104).

As shown in FIG. 1, in the file distribution table 3, "01" and "A: \ P" are set as a set of a directory identifier and an absolute path name to the directory.
ROJ \ WORK "," 02 "and" B: \ NEC \ GU
"I", "03" and "A: \ JOB \ TMP" and "0"
4 ”and“ B: ¥ FDD ”are registered respectively.

On the other hand, when the user saves a file newly created by an application program such as a word processor or a spreadsheet, the file name ( The first two characters of the actual file name are the directory identifier (file distribution table 3) corresponding to the absolute path name to the directory to be distributed.
(The one registered in advance) is added to the temporary file name and temporarily saved in an arbitrary directory.

Now, in the pre-execution file system 4 illustrated in FIG. 4, for example, the temporary file name “02GUI.D” is used.
OC "and" 04PLAN. Two files of "XLS" are temporarily stored in the directory of the absolute path name "A: \ TMP", and the temporary file name "01SIRYO. TXT "and" 03 NEC. It is assumed that two files "JAW" are temporarily stored in the directory (root directory) having the absolute path name "A: \".

Next, the user activates the file allocating means 2 in order to allocate the temporarily stored file to a predetermined directory.

The file allocating means 2 first searches the file allocating table 3 (step S201),
It is determined whether or not information is registered in the file allocation table 3 (step S202), and if not registered, the processing is immediately terminated.

On the other hand, when the information is registered in the file distribution table 3 (YES in step S202), the file distribution means 2 uses the two-letter directory identifier registered in the file distribution table 3 for the head side. One by one is set and set as a search key (step S203), the files stored in all directories of all drives are searched, and the file names of all files are acquired (step S204). For example, MS-DO
In the case of S, the DIR command is used to acquire all file names in all directories of all drives.

Next, the file sorting means 2 determines whether or not the search key and the first two characters of the obtained file name match (step S205). If the search key matches the first two characters of the file name (step S
Yes in 205), the file distribution unit 2 changes the file name (temporary file name) to a file name (actual file name) with the first two characters removed, and the file distribution table 3 corresponds to the directory identifier of the search key. The file is moved to the directory having the absolute path name registered in step S206. For example, in the case of MS-DOS, the first two characters of the temporary file name are replaced with the corresponding absolute path name to obtain the absolute path name to the file, and then the RENAME command is used to move the file to the corresponding directory. To do. When the search key and the first two characters of the file name do not match (NO in step S205), the file distribution unit 2 skips step S206.

Next, the file distribution means 2 judges whether or not the acquired file name still exists (step S
207), the control is returned to step S205, and steps S205 to S207 are repeated.

If the file name disappears in step S207, the file distribution means 2 determines whether or not the directory identifier registered in the file distribution table 3 still exists (step S208). Return the control to S203,
Steps S203 to S208 are repeated.

When the directory identifier registered in the file allocation table 3 is exhausted in step S208, the file allocation means 2 ends the process.

As a result of the execution of the file allocating means 2, in the pre-execution file system 4 and the post-execution file system 5 illustrated in FIG.
GUI. The file of "DOC" is the actual file name "GUI. Changed to "DOC" and the absolute path name "B:
It is moved to the directory indicated by "\ NEC \ GUI" and the temporary file name "04PLAN. The file "XLS" is the actual file name "PLAN. It is changed to "XLS" and moved to the directory indicated by the absolute path name "B: \ FDD." The temporary file name "01SI
RYO. The file “TXT” has the same file name as the actual file name “SIRYO. It is changed to "TXT" and moved to the directory indicated by the absolute path name "A: \ PROJ \ WORK", and the temporary file name "03 NEC. The file of "JAW" is the actual file name "NEC. JAW ”
And is moved to the directory indicated by the absolute path name “A: \ JOB \ TMP”.

As described above, in the file allocation method of the present embodiment, when saving a file, the directory identifier corresponding to the absolute path name to the desired directory is added to the first two characters of the file name (actual file name). If added and temporarily stored, the files can be collectively distributed under the directory to be arranged without the work of searching and describing the directory by the absolute path name on the storage medium later.

Although the directory identifier is made up of two characters in the above embodiment, it goes without saying that it may be one character or three or more characters.

[0031]

As described above, according to the present invention, a group of a directory identifier and an absolute path name to a directory is registered in advance in the file distribution table by the distribution table registration means, and the file distribution means registers the file name in the file name. When the included directory identifier matches the directory identifier registered in the file distribution table, the file is automatically distributed to the directory with the corresponding absolute path name. You don't have to know the whole structure and you can save time searching and selecting the directory to save the file.
This has the effect of simplifying file management.

Further, there is an effect that it is possible to reduce the labor and mistake of the work associated with designation and classification by the absolute path name of the directory, which is a weak point of the conventional file system, and the work of file management.
