FILE NAME MANAGEMENT METHOD AND FILE NAME MANAGEMENT DEVICE

摘要

In the disclosed method and device for managing file names, a fixed-length extraction unit (103) extracts a fixed-length character string from a file name that has been input, and outputs a fixed-length file name signal (S103). A computation unit (104) performs a process computing a checksum, CRC, or the like of the input file name, and outputs a post-computation file name signal (S104). A linking unit (105) outputs a linked signal (S105) wherein the aforementioned fixed-length file name signal (S103) and the aforementioned post-computation file name signal (S104) are associated, and the file name linked thereto is held and recorded in a file name recording unit (106). When searching for a given file name among the plurality of file names that are recorded, a search is performed for a match with the computation results of the aforementioned computation unit (104). Consequently, the volume of memory that records file names is reduced while aiming to increase the speed of searching for file names.
