If your memory stick is formatted using FAT (Sometimes also called
FAT16) there are several limitations you might want to know about
- Partition (drive letter) is limited to 2 GB in total size.
- Root directory is limited to 512 entries (an entry is a file or a
directory), although subfolders can contain more than 512 entries.
- Max number of files on the entire drive is 65,517.FAT32 removes most of the above limitations, so if you can you might
want to re-format your memory stick using FAT32. However you will want
to first verify that your camera / picture frame can read memory sticks
formatted with FAT32 (most modern devices made should be able to).
Of course you can also format your memory stick using NTFS, but that
will most likely restrict your memory stick to only working with Windows
NT or later.
