4 0x6D 0x07 0x01 0x02
6 ^{'READ_CD_FILE'.}
・3rd-4th byte : The file number (m) of the head which can carry out
information acquisition is outputted.
・5th-6th byte :The total file number of a file system analysis result is
outputted. When analysis is not completed, the number of files which
analysis has ended is outputted.
・Outputs the number of folders in the file system analysis result.
・Outputs the value in Little Endian format.
・1st-2nd byte : the folder information acquirable number of a file system
analysis result (n). The folder information to this number can be read at
READ_CD_FONUM 4 0x6D 0x07 0x01 0x03
6 ^{'READ_CD_FOL’.}
・3rd-4th byte : The folder number (n) of the head which can carry out
information acquisition is outputted.
・5th-6th byte :The total folder number of a file system analysis result is
outputted. When analysis is not completed, the number of folders which
analysis has ended is outputted.
・Outputs information of the L[15:0]={M, N}^th file in the file system analysis
result.
(For L, Please set up L between file information acquirable numbers
READ_CD_FILE
4 0x6D 0x08 N M
64
[1st-2nd byte of 'REDA_CD_FINUM'] from 1.)
・The information is output in Little Endian format.
・When file system analysis is not completed, the maximum of specified L
is recorded as information read-out completion.
The acquired information may become invalid when analysis is resumed.
