Abstract

PURPOSE:To improve the working efficiency by adopting block constitution consecutive entirely for a file in a disk so as to quicken the load time of the file in case of file copy. CONSTITUTION:In sorting contents A-4, A-5 in succession to the content A-3 of a file A while disks 2, 3 are in the state as shown in figure (a) at present time, the file contents A-4, A-5 generated by a graphic display with a keyboard are stored in block 231, 232 of a temporary storage area 23 of the disk 2 as shown in figure (b) by a store instruction. Then a block 33 storing file content A-3 of the disk 3 is detected at the interval of other processings such as edition and file contents B-1, B-2, C-1, C-2 in blocks 34-37 in succession to said block 33 are moved to blocks 36-39 by two blocks corresponding to the file data A-4, A-5. Further, the tile contents A-4, A-5 in the blocks 231, 232 of the disk 2 are moved to th blocks 34, 35 of the dead disk 3.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a file management method for a stand-alone work system.

[Conventional technology]

In traditional stand-alone work system file management schemes, each file is accessed in blocks. In addition, the disk configuration of this type of system consists of an OS area, a work area, and a storage area, and the files in the OS area and work area always have a contiguous block configuration on the disk, but each storage area Since data increases or decreases for each file, it is possible to store files even if they are not continuous blocks.

FIG. 3 shows a file management method of a conventional stand-alone work system. As shown in FIG. 3(a), the disk 2 has an OS area 21, a work area 22, and a storage area 23, and blocks 231 to 237 of the storage area contain the contents of files A-1 to A-1.
-3. Contents of file B B-1 to B-2. Contents C-1 to C-2 of file C are stored. When the contents A-4 to A-5 of file A are stored in this, the contents A-1 to A-3 and A-4 to A- of file A are stored in blocks 238 and 239 as shown in Fig. 3(b). 5 is not accommodated in consecutive blocks.

[Problem that the invention seeks to solve]

As mentioned above, in the file management method of conventional standalone work systems, in the storage area,
When loading and storing files, the blocks are not necessarily contiguous, so it may be necessary to search all the shillings on the disk to find one block.

The load and store times for small data files are not much different from those for files with a continuous block structure, but for large data files, the number of operations of the disk device head becomes extremely large.
Since the time required for loading and storing increases significantly, there is a problem that work efficiency deteriorates.

[Means for solving problems]

The method of the present invention prepares a first disk that uses the operating system area, work area, and other remaining blocks as a storage area, and a second disk that is used exclusively for the storage area, and stores file data. In this case, the file data is first stored in a storage area of the first disk, and then a block in which file data preceding the file data is stored is detected from the second disk, and a block subsequent to the file data is detected from the second disk. The content stored in the block is moved by a block corresponding to the file data, and the file data is stored in the block that becomes empty as a result of the movement, and the storage of the file data on the second disk is continuous. Constructed using blocks.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention. The file management system of the stand-alone work system shown in Figure 1 consists of a central processing unit 1, disks 2 and 3, a graphic display 4 with a keyboard for displaying graphic data, comments, etc. and inputting commands, and a system startup system. It consists of a keyboard 5 for inputting commands such as the following.

Disk 3 is dedicated to storage area and Disk 2
The OS area 21, the work area 22, and the remaining blocks are provided as a storage area 23, and this storage area 23 is used for temporary storage, so that it is not necessarily necessary to use consecutive blocks.

The procedure for storing files is shown below.

Assume that files are currently stored on disks 2 and 3 in the state shown in FIG. 2 (a>).

That is, on disk 2, OS area 21. The storage area 23 following the work area 22 is empty, and the contents of files A-1, A-2, A are stored on the disk 3.
-3 is stored in blocks 31, 32 and 33, contents B-1 and B-2 of file B are stored in block 34.35, and contents C-1 and C-2 of file C are stored in block 36.37. . In this state, content A of file A follows content A-3.
The case where -4 and A-5 are stored will be explained.

File contents A-4 and A-5 created on the graphic display with keyboard are stored in block 231. of the temporary storage area 23 of disk 2 by a store command.
232 as shown in FIG. 2(b).

Next, during other processing such as Nibite, block 33 in which file content A-3 of disk 3 is stored is detected, and blocks 34, 35, and 36 following this block 33 are detected.
．． File contents in 37 B-1, 8-2, C-1, C
-2 to blocks 36 to 39 as file data A-4, A
-5, and then file contents A- in blocks 231 and 232 of disk 2.
4. Block 34.3 of disk 3 where A-5 is empty
Move to 5.

By doing so, the file stored on the disk 3 can use continuous blocks, and the loading time when copying a file to another disk can be shortened.

〔Effect of the invention〕

As described above, the present invention has the effect that by making all the files on the disk into a continuous block configuration, the file loading time during file copying becomes faster and work efficiency can be improved.

[Brief explanation of drawings]

FIG. 1 is a block diagram showing an embodiment of the present invention, FIG. 2 is an explanatory diagram illustrating the management system shown in FIG. 1, and FIG. 3 is a diagram illustrating a conventional management system.

Claims (1)

[Claims] A first disk that uses an operating system area, a work area, and other remaining blocks as a storage area, and a second disk that is used exclusively for the storage area are prepared, and when storing file data, first stores the file data in the storage area of the first disk, then detects from the second disk a block in which file data preceding the file data is stored, and stores data subsequent to the block. The content stored in the block is moved by a block corresponding to the file data, and the file data is stored in the block that becomes empty as a result of the movement, and the file data is continuously stored in the second disk. A file management method for a standalone work system that uses blocks.
