Detailed Description of the Invention [Field of Application of the Invention] The present invention relates to a file management information processing device that processes management information for managing a large number of files stored in an auxiliary storage device such as a computer device, and particularly relates to a file management information processing device that processes management information for managing a large number of files stored in an auxiliary storage device such as a computer device. This is suitable for use when displaying on a display device.

[Background of the invention]

A computer device, for example, what is generally called a personal computer device or a business computer device, stores and holds files, which are a collection of takes or a collection of programs, in an auxiliary storage device such as a floppy disk device or a hard disk device. A large number of files stored in these auxiliary storage devices are managed by a file management information storage table. The file management information storage table has a large number of file management information storage sections set corresponding to each file in order to manage each of a large number of files, and each file management information storage section is necessary for managing the corresponding file. For example, various information is stored, such as the file name, the content of the file, and the location information of the Tinuku device in which the file is stored. Then, when a file is added to the disk device or deleted from the Tinuku device, the contents of the file management information storage section are updated. This glaze file management is generally performed by the operating system, which is the basic program of the computer device. Storage of file management information in a conventional file management information storage table of this type was completely optional. That is, in general, when files are added and stored sequentially, the file background information is written sequentially from the addition II (+K file storage management table) to the file management table and l!i! information storage section. ．It is done.

However, if you delete a file in the middle, the file management information of the next newly added file will be stored in this file management information record 1. is written in section 1: is done.

Generally, an operating system includes a file management information display control means for sequentially displaying the file names of a large number of files stored in a Tinuku device or the like on a display device. This extracts necessary information from each file management information storage section of the file management information storage table and displays it in sequence.

This display order is predetermined and corresponds to the arrangement order of the file management storage units in the file management information storage table.

This configuration is extremely effective in dynamically managing files, and greatly reduces the number of man-hours required for the computer operator. However, a file management information storage section in which the file management information is arranged next to the file management information storage section in which the file management information is stored in front 1;
Alternatively, the file can be arbitrarily stored in the empty file management storage unit after the file has been deleted. Therefore, when the number of stored files increases, it becomes difficult for the operator to search for the desired file from among the large number of file names displayed on the display device by the display control means. However, it is difficult and inconvenient to operate.

Regarding file management, see JP-A No. 58-166446,
