A:Answer This player can play video, audio and photo files contained in the disc or USB device. This player supports USB flash drive/external HDD formatted in FAT32 and NTFS when accessing files (music, photo, movie). However, for BD-Live, use the USB flash drive / external HDD formatted in FAT32. This unit can support up to 4 partitions of the USB device. A USB device which requires additional program installation when you have connected it to a computer, is not supported. If you use a USB extension cable, USB HUB or USB Multi-reader, the USB device may not be recognized.
