3.3 Subdirectory operation To access files in the

subdirectory, it is necessary to set the current directory information by calling the following function.

Read directory information (GFS_LoadDir)
Current directory setting (GFS_SetDir)

∙ You can use it by reading the directory information in advance and eliminating the CD-ROM access at the time of opening the file.

(1) Load directory information (GFS_LoadDir)

Specify a sub-directory file to read and hold directory information.
At this time, the following two types can be selected as the directory information holding area.

(a)GFS_DIR_ID

Does not retain the file name. Only access by file identifier is possible.

(b)GFS_DIR_NAME

Since the file name is retained, a larger area than (a) is required.
Access by file name is possible.

(2) Set current directory (GFS_SetDir)

The directory information area read by GFS_LoadDir is the current directory.
