All Files under catalogue is shown to user.In such a case, it is possible to the operating system of configurating terminal device is so that locate
Reason unit 12 judges to whether there is specific markers in the file header of the file under this catalogue when executing directory.For example, such as
There are specific markers, then processing unit 12 in the file header of certain file under fruit processing unit 12 this directory result of determination
Can determine presence second file corresponding with this document in system recovery region, and this document is the copy of the second file
(the first file).In this case, because the first file and the second file have identical filename and logical address, therefore
In order to avoid after performing directory, showing the first file and the second file in directory result simultaneously, permissible
The operating system of configurating terminal device is so that processing unit 12 is deleted and the second file phase in the Query Result of this directory
The query term closing, thus avoid the generation of mistake.If additionally, processing unit 12 determines first under this directory structure
There are not specific markers, then processing unit 12 can determine do not exist and this article in system recovery region in the file header of file
Corresponding second file of part.In this case, processing unit 12 need not be modified to directory result.
By above-mentioned configuration, the file (the second file) needed in operating system recovery and its copy (the first file) are simultaneously
In the presence of, processing unit 12 can be determined by the specific markers in the first file and is being when executing directory
System recovers to exist second file corresponding with the first file in region.In this case, processing unit 12 is tied in directory
Delete query term corresponding with the second file in fruit, thus avoid appearance two in directory result to have identical file
The appearance of the file of name and logical address.Additionally, in the case that user wishes that execution system is recovered, processing unit 12 only needs
Directly delete the file in the file storage area in memory element 11, and based on the system recovery region in memory element 11
