Abstract

PROBLEM TO BE SOLVED: To prevent an unnecessary file from being left on a hard disk by deleting a corresponding file on the hard disk when the file in a retrieval directory meets a file deletion condition. SOLUTION: A deletion control part 2 stores a directory, generated by classifying files stored on the hard disk, as the retrieval directory 10. Further, the deletion control part 2 is stored with the previously set file deletion condition 11 and information 12 on whether directory deletion is needed or not. A file deleting means 3 judges whether or not a file in each retrieval directory meets the file deletion condition 11 and deletes the file on a corresponding hard disk when the condition is met. Further, a directory deleting means 4 deletes a directory on the hard disk when there is not file in the retrieval directory 10 and the information 12 on whether directory deletion is needed indicates 'needed'.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for temporarily storing files such as an error / trace log and statistical information on a hard disk. Related to the device.

[0002]

2. Description of the Related Art Conventionally, in various systems using a computer, it is known that files such as an error / trace log and statistical information are stored on a hard disk. In such a system, in order to avoid unnecessary files accumulating on the hard disk and making it difficult to manage, usually the program that created the files determines the usefulness of each file, Deletes it from the hard disk.

[0003]

However, in such a system, a file created by a backup function or the like may remain on the hard disk due to an intermittent failure of various programs or abnormal termination of the system. Files left in this way are often unnecessary when there is a legitimately created file.Therefore, if many such unnecessary files accumulate, it becomes difficult to manage them for later processing. It will be.

In order to solve such inconveniences, not only the program that created the file as described above, but also a system that activates the file has an algorithm that detects unnecessary files and deletes them. Must-have. However, in that case, for each program,
Further, since an algorithm for detecting / removing unnecessary files is required for each system, there is an inconvenience that it takes time and cost to develop the system.

[0005] The present invention has been made in view of the above circumstances, and a purpose thereof is to automatically detect / unnecessary files among files stored in a hard disk.
An object of the present invention is to provide an unnecessary file deleting apparatus which deletes unnecessary files from remaining on a hard disk.

[0006]

According to the unnecessary file deleting apparatus of the present invention, a directory created by classifying files stored in a hard disk by management type is stored as a search directory, and a preset file is stored. A deletion control unit for storing a deletion condition and a directory deletion necessity; and determining whether or not a file in the search directory of the deletion control unit meets the file deletion condition. File deletion means for deleting the file in the hard disk corresponding to the file in the file, and when there is no file in the search directory of the deletion control unit and it is necessary to delete the directory, To delete the directory on the hard disk And tri-deleting means, the file deletion unit and directory deleting means, is executed every predetermined cycle, and that a monitoring means for waiting for them in the meantime was solutions of the problems.

According to this unnecessary file deleting apparatus, the unnecessary file among the files in the search directory stored in the deletion control unit, which meets the file deleting condition, is provided by providing the file deleting means. The file is detected, and the corresponding file on the hard disk is deleted. Further, since the directory delete means is provided, an unnecessary directory among the search directories, that is, a search directory in which there is no file and the necessity of directory deletion is required, is detected, and the corresponding hard disk is further searched. The directories inside are deleted. In addition, since these deletion processes are executed at predetermined intervals by the monitoring means, unnecessary files and unnecessary search directories are prevented from remaining on the hard disk beyond the predetermined interval.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an unnecessary file deleting apparatus according to the present invention will be described in detail. FIG. 1 is a block diagram showing a schematic configuration of an embodiment of an unnecessary file deletion device according to the present invention. In FIG. 1, reference numeral 1 denotes an unnecessary file deletion device, and the unnecessary file deletion device 1 includes a deletion control unit 2.
, A file deleting unit 3, a directory deleting unit 4, and a monitoring unit 5.

FIG. 2 is a module configuration diagram showing an example of a system in which the unnecessary file deletion device is used. In FIG. 2, reference numeral 6 denotes a hard disk connected to a computer (not shown). This hard disk 6
An error / trace log function module 7 and a statistical information collection / accumulation function module 8 provided in the computer (not shown) are connected to be accessible, and are also connected to the unnecessary file deletion device 1 so as to be accessible. Alternatively, this is stored.

[0010] The error / trace log storage function module 7 creates a file 9 which records the movements and results of individual steps of a program for debugging when an error occurs in each system of the computer, and stores it in a hard disk. 6, or writes the record into a file that has already been created. The statistical information collecting / accumulating function module 8 includes a file 9 storing information transferred on a network or a line.
Is created and stored in the hard disk 6, or the record is written in a file that has already been created. When the files 9 created in this way are stored in the hard disk 6, they are classified by management type, that is, each file 9 relating to an error / trace log and each file 9 relating to statistical information. Are stored in directories (not shown) created for each classification.

The unnecessary file deletion device 1 is provided in a computer (not shown) and can access the hard disk 6 together with the error / trace log storage function module 7 and the statistical information collection / storage function module 8 as described above. Or stored in the hard disk 6, and stored in the file 9 in the hard disk 6.
Are monitored at predetermined intervals to delete unnecessary files 9 from the hard disk 6 and also delete unnecessary directories (not shown) from the hard disk 6.

As shown in FIG. 1, in the unnecessary file deletion device 1, the deletion control unit 2 searches the directories created by classifying the files 9 stored in the hard disk 6 as described above. It is formed so as to be automatically stored as a directory 10. The search directory 10 stores the name of each file 9, the date and time of generation, and the like. In the deletion control unit 2, a file deletion condition 11 and a directory deletion necessity 12 which are set in advance by being input from an input means (for example, a keyboard) of a computer or the like when the unnecessary file deletion device 1 is created. Is stored.

The file deletion condition 11 is defined by, for example, a file name or a file creation date and time, and specifically includes the following conditions. (A) If the file name matches a predetermined deletion file name or has the deletion file name as a part, delete this. (B) If the file creation date and time exceeds a predetermined storage period, delete it. (C) When the file creation date and time indicated by the character string of the file name exceeds a predetermined storage period, this is deleted.

The directory deletion necessity 12 determines whether or not to delete a directory in the hard disk 6 corresponding to the search directory when there is no file 9 in the search directory 10 as described later. In this case, "required" is set in advance to delete, and "no" is set in case of leaving without deleting. The deletion control unit 2 having the search directory 10, the file deletion condition 11, and the directory deletion necessity 12 is formed of a text file, and thus can be applied to any type of computer. It has become.

The file deletion means 3 in the unnecessary file deletion device 1 determines whether or not the files 9... In each search directory 10 stored in the deletion control unit 2 satisfy the file deletion conditions 11, respectively. And
If the file matches, the file 9 in the hard disk corresponding to the file 9 in the search directory is deleted. In other words, the search directory 10 only stores the name of each file 9 and the date and time of generation as described above, and the contents are stored in the hard disk 6 only. If it is determined whether or not each file 9 conforms to the file deletion condition 11, it is possible to determine whether the file 9 directly complies with the file deletion condition 11 from a directory in the hard disk 6. In comparison, the process is faster.

The directory deletion means 4 in the unnecessary file deletion device 1 determines whether or not each of the search directories 10 stored in the deletion control section 2 has a file 9 therein. It is checked whether the directory deletion necessity 12 is “necessary” or “no” only in the case of. When there is no file in the search directory 10 and the directory deletion necessity is “necessary”,
The directory corresponding to the search directory 10 in the hard disk 6 is deleted.

The monitoring means 5 is connected to a timer built in, for example, a computer (not shown) to detect the time, and input means (for example, a keyboard) of the computer in advance.
The file deletion unit 3 and the directory deletion unit 4 are executed at predetermined intervals (for example, 24 hours, 48 hours, 168 hours, or the like) which are set by inputting from the like or when the unnecessary file deletion device 1 is created. , And in the meantime, they are put on standby.

Next, the operation of the unnecessary file deleting apparatus 1 having such a configuration will be described with reference to the flowchart of FIG. When the unnecessary file deletion device 1 is started, first, the deletion control unit 2 is read into a memory (not shown) of the computer (Step 1, hereinafter referred to as ST1). In this manner, the deletion control unit 2, that is, the search directory 10, the file deletion condition 11, the directory deletion necessity 1
When the file 2 is read, the search file 10 is extracted (ST2), and the file 9 is extracted from the extracted search file 10 (ST3).

When the file 9 is extracted in this way, the file deleting means 3 is activated to determine whether or not the extracted file 9 satisfies the previously read file deletion condition 11 (ST4). . If it is determined that the file 9 meets the file deletion condition 11, the file 9 in the hard disk 6 corresponding to the file 9 is deleted (ST5).

If the file deletion condition 11 is not satisfied, the file deletion means 3 does not delete the file 9 in the hard disk 6 corresponding to the file 9 and the search directory 10 is further deleted. It is detected whether or not any other file 9 remains therein (ST6). If there is any remaining file 9, the process returns to ST3 and the file 9 is extracted. Thereafter, when all of the extracted files in the search file 10 satisfy the ST3 and ST4 and the file deletion condition 11, the process of ST5 is repeated.

The search file 10 thus extracted
When each process is completed for all the files in the directory, the directory deletion means 4 is activated and the extracted search file 10 is deleted.
It is determined whether or not the file 9 is present, that is, whether or not the search file 10 has already been deleted from all the files 9 (ST7). If it is determined that there is no file 9 in the extracted search file 10, it is determined whether the previously read directory deletion necessity is "necessary" or "no" (ST8). If it is determined to be "necessary", the directory on the hard disk 6 corresponding to the search directory 10 is deleted (ST9).

The directory deletion necessity 12 is “No”.
In the case of, the directory deletion means 4 does not delete the directory in the hard disk 6 corresponding to the search directory 10, and no other search directory 10 remains in the deletion control unit 2. Is detected (ST10), and if it remains, the process returns to ST2 to extract the search directory 10.

Thereafter, the processing of ST3 to ST9 is repeated for all the search files 10 remaining in the deletion control unit 2, and when all of these processings are completed, the monitoring unit 5 waits for a predetermined cycle (ST11). After the predetermined period elapses, the processes of ST1 to ST11 are repeated again. As shown in FIG. 3, if it is determined in ST7 that there is a file 9 in the search file 10, the process proceeds to ST10, and the necessity of directory deletion is determined to be "NO" in ST8. If it is determined, the process proceeds to ST10.

In the unnecessary file deleting apparatus 1 which operates as described above, since the file deleting means 3 is provided, the unnecessary file deleting apparatus 1 includes the files 9 in the search directory 10 stored in the delete control unit 2. Unnecessary files 9 can be detected, and the corresponding files 9 on the hard disk 6 can be automatically deleted. In addition, since the directory deletion means 4 is provided, an unnecessary search directory 10 among the search directories 10... Can be detected, and a corresponding directory in the hard disk 6 can be deleted. Since these deletion processes are executed at predetermined intervals by the monitoring means 5, unnecessary files and unnecessary directories can be prevented from remaining on the hard disk 6 beyond the predetermined interval.

Incidentally, such an unnecessary file deleting apparatus 1
According to the above, if the file generation source program uses the file 9 during the processing, the file may not be deleted. In this case, the file deletion processing is automatically performed by the next deletion processing after a predetermined period. Therefore, unnecessary files do not remain in the hard disk 6 for a long period of time.

In the above embodiment, the case where the modules provided in the computer are the error / trace log function module 7, the statistical information collection / storage function module 8, and the like has been described. However, the present invention is not limited to this. Without being limited to this, the present invention is also applicable to a case where, for example, a function module is provided for charging data, operation history, an i / f data file between programs, and the like.

[0027]

As described above, the unnecessary file deleting apparatus according to the present invention can reduce the number of unnecessary files and directories out of the files generated by various programs and the directories managing the files beyond a predetermined period. Because it is designed to prevent remaining in the hard disk, it prevents intermittent failures of programs that create / write files, and unnecessary files that occur due to abnormal termination of the system from remaining in the hard disk. Thus, the stability of the system can be improved.

Since unnecessary files can be prevented from remaining in the hard disk, unnecessary files are detected in both the program that created the file and the system that starts the file, and are deleted. There is no need to have an algorithm,
Therefore, the number of program development steps can be reduced, and the development time and development cost can be greatly reduced.
