FILE MANAGEMENT APPARATUS AND FILE MANAGEMENT METHOD
First Claim
1. A file management apparatus for processing a file stored in an external storage device, the file management apparatus comprising:
- a target file specifier for specifying a file to be processed as a target file among a plurality of files stored in the external storage device;
a temporary storage capable of loading and unloading files in time shorter than the time required for the external storage device to load and unload files;
a target file acquirer for reading the target file from the external storage device and storing the target file in the temporary storage; and
a processing executer for performing a processing operation determined for the target file stored in the temporary storage.

Abstract
In a file management apparatus, on detection of the user'"'"'s file selecting action, a high-speed file processing execution program P2 gives an instruction to a cache driver D2 to read a selected target file from an external storage device and store the read target file into a cache memory CM. When a file processing operation for the selected target file is determined by the file processing program P1, the file processing program P1 gives an instruction to the cache driver D2 to write the target file, which is stored in the cache memory CM, in the memory location represented by a newly specified address in the external storage device. The file management apparatus effectively shortens the time required for executing a processing operation for a file stored in the external storage device.

11. A computer program product, comprising:
-
a computer-readable medium having file management program embedded therein to process a file stored in an external storage device, the file management program comprising; a program code for specifying a file to be processed as a target file among a plurality of files stored in the external storage device; a program code for reading the specified target file from the external storage device and storing the read target file into a temporary storage, wherein the temporary storage is configured to enable file reading therefrom and file writing thereto in a shorter time period than a time period required for file reading from and file writing into the external storage device; and a program code for performing a processing operation determined for the target file stored in the temporary storage.
