I have a Pandigital too and although I don't think the users guide mentions it (major oversight on their part), the root directory on this thing can only hold a limited # of files/folders (mine is limited to 108) If I understant it correctly, it's due to the fact that the pandigital uses a FAT (file allocation table) storage method - not that the reason matters. The solution is: make folders in the root directory (you could have up to 108 folders on my pandigital) and I believe each subfolder can have an unlimited number of files in it. I just call my subfolders "Dec 2009 additions, Jan 2010 additions, etc). The Pandigital will randomly cycle thru files in each of these subfolders just as if they were in the root directory. Hope this helps.

You can also format the frame in the FAT32 file system. Then you don't have to worry about folders.
