Remarks
-The LSI first starts playing the playable
files in the root folder, if any.
-The files are played in the ascending
order of UNICODE given to each file
name.
-After playing all the playable files in the
root folder, the LSI searches folders in
the lower hierarchy.
-The folders are searched in the
ascending order of UNICODE given to
each folder name.
-Unplayable files are ignored.
-After playing all the playable files
including those in A_FOLDER and in its
lower hierarchy, the LSI moves to the
hierarchy in which A FOLDER exists and
searches files.
-In this case, since no playable file exists
in D FOLDER, which is in the same
hierarchy of A_FOLDER, the LSI plays
the playable files in E FOLDER in the
further lower hierarchy.
14.5 Search within multi-drive and multi-partition
If a device is a multi-drive type, the LSI recognizes the drive having the smaller LUN (Logical Unit Number) for the
supporting FAT.
Only one drive is recognized and the other drive is not.
For the multi-partition, the LSI recognizes only the first read FAT-supported partition.
Files in other partitions cannot be read.
14.6 External HUB search
When the USB connector is connected to a HUB, and a FAT-supported drive is connected ahead of the HUB at
mounting the USB for this LSI, only one drive is recognized.
The LSI does not support external HUBs, it cannot detect plugging/unplugging of the drive ahead of the HUB after the
USB is mounted.
