"Hidden Folders"?! I haven't heard of such a thing, or seen them. Let me put it this way: 1.) I wiped the C drive so there was no operating system, and the computer wouldn't boot up. 2.) I did the same with my D drive (data) 3.) I reinstalled Windows XP, and clearly chose FAT32. 4.) I've been reinstalling all my software. Here's a composite screenshot from My Computer, which shows both my hard drives as FAT32. Ron
