About files and folders on the device
The player may be unable to play back the media due to
incorrect format or file specification.
Files may be grouped into folders, and the folders organized
under “Root” folder, which represents the connected media.
The player can detect and play back the folders which are
located up to the fifth layer.
The files in the SMART NAVI display are arranged by the

different media, depending on the numbers of folders and
files recorded, etc.
The player recognizes up to 1,000 files per folder, and up to
