How big can Memory Cards/USB drive be in capacity?
About this aspect:
Our frames can read SD cards and USB drives up to 32GB. However, bear in mind that if there are thousands of files on your card and they are in different folders or formats (i.e. MP3, .avi, .txt etc.,) this will probably slow the frame's processor.
If you're just dealing with JPEG's for example, you should be able to view as many as your card contains. Also, if the frame does not appear to be reading a card, it is worth checking the 'Properties' of your USB drive or SD card and ensuring that 'FAT' or 'FAT32' is selected.
Some things to consider:
Our frames can only detect USB 2.0
File system should be FAT32
