Unfortunately, you cannot go back to FAT32 from NTFS once you have done a conversion. You'll have to reinstall and reformat the drive. I'm assuming the folder that you're talking about is the one tied to your user account in C:\Documents and Settings\ The easiest way to fix this is to log on in as the administrator, create a new account with the correct name, and copy the files from your old folder into the new folder using Windows Explorer. Again, you must do this from the Administrator account.
