Currently DP330 can only support the standard file format in FAT32 system. If the USB storage device or SD memory card has been formatted differently (such as NTFS or exFAT), then DP330 will display the “Unsupported File System” message when such storage device is inserted. Please change the storage device or memory card and use only the media formatted for FAT32. Alternatively, the user may need to use a PC to convert the media into FAT32 format.
