DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for searching for unnecessary recording media, and more particularly to a method for displaying a list of unnecessary recording media.

[0002]

2. Description of the Related Art Unnecessary recording media have conventionally only been deleted in file units, but not in recording medium units. Therefore, in order to search for an unnecessary recording medium, it is necessary to manually search all the same files in a plurality of recording media to determine that the recording medium is unnecessary.

[0003]

As described above, conventionally, since all the same files existing in a plurality of recording media are not managed, means for retrieving unnecessary recording media from a plurality of recording media is provided. Did not. Therefore, there is a problem that all the same files existing in a plurality of recording media must be manually checked in order to determine that the recording media are unnecessary recording media.

Therefore, an object of the present invention is to solve the above-mentioned problem, and when searching for an unnecessary recording medium, all the same files existing between a plurality of recording media are not required, and the number of steps can be reduced. An object of the present invention is to provide an unnecessary recording medium selection method that can avoid erroneously determining a necessary recording medium as an unnecessary recording medium.

[0005]

In order to achieve the above-mentioned object, an unnecessary recording medium selecting method according to the present invention uses an external storage device for an operator to insert a recording medium and information read from the external storage device. In the unnecessary recording medium selection method including a processing unit that processes the file information and stores the file information as recording medium information, and an input / output device that performs a list display and selection of unnecessary recording medium information among the recording medium information, A processing unit that creates and processes the file information, outputs a file information creation processing unit, a plurality of recording medium information storage units that store a plurality of records that store the file information output from the file information creation processing unit, A file information comparison processing unit for comparing and updating a plurality of storage medium information storage units and deleting unnecessary storage media and corresponding storage medium information storage units; Record has the same file number storage unit that stores the same file number of file information and the file information storage unit that stores the file information, and searches whether the same file exists in a plurality of recording medium information storage units. Then, an unnecessary recording medium information storage unit is presented.

Further, the file information comparison processing section compares the file information storage section of the record with the file information storage section of the record in the recording medium information storage section previously output by the file information creation processing section, and determines the same record. It is preferable to search.

Further, when the same record exists, it is preferable that the file information comparison processing section adds 1 to the same file number storage section of the recording medium information storage section and updates the same record of the recording medium information storage section. .

[0008] Further, the file information comparison processing unit may include:
It is preferable that all the storage medium information storage units having the same file number storage unit of one or more are displayed on the input / output device.

It is preferable that the input / output device notifies the file information comparison processing section of a list of the recording medium information storage sections selected by the operator among the displayed recording medium information storage sections.

[0010] Further, the file information comparison processing section is provided with a file information storage section of the record in the recording medium information storage section notified from the operator through the input / output device, and a file file of the record in all other recording medium information storage sections. It is preferable to compare with the information storage unit and search for a record in which the same file information storage unit is set.

Still further, the file information comparison processing unit includes:
When a record in which the same file information storage section is set can be searched, 1 is subtracted from the value of the same file number storage section of the record in which the same file information storage section is set, and the recording medium information storage section is retrieved. It is preferable to update.

Further, it is preferable that the file information comparison processing section deletes the recording medium information storage section notified by the operator after the update of the same file number storage section of the record of the recording medium information storage section is completed.

The unnecessary recording medium selection method of the present invention is,
An unnecessary recording medium is searched for from a plurality of recording media and presented.
More specifically, it has a file information comparison processing unit that displays a recording medium information storage unit corresponding to an unnecessary recording medium among the plurality of recording medium information storage units output by the file information creation unit on the input / output device.

With the above configuration, in the present invention, information of a recording medium having all the same files existing among a plurality of recording media is presented to an operator. Therefore, it is not necessary to manually check all the same files existing in a plurality of recording media.

[0015]
