The FAT32 format is significantly inferior to NTSF, I highly recommend converting your drive to NTFS. You don't need to reformat, you can just convert it:

How to convert a FAT16 volume or a FAT32 volume to an NTFS file system in Windows XP

Yes just use the convert coomand it will not harm any files etc.
It may say cannot convert at this time just reboot pc and it will be done.

ok it said it couldnt convert and would i like it to do so when the computer reboots.. i clicked yes then restarted then the oc ran checkdsk then teh conversion started determining free space or w/e then it said conversion failed.. i didnt catch why as it flashed across the screen too fast then windows started up like normal... i have well over 300gb free space so that cant be the reason... any idea why i cant convert?

soooo any idea?

Hello again,so are they large files you are trying to copy?Bigger than 2 gig?

Is there files contained in the the file or folder you are trying to move?

EXAMPLE:Several movies?

Can you not open the file and move several smaller items at a time?

Computer Knowledge - Why Can't I Copy a Large File Despite Having Larger Free Space?

its one big file (4.5gb) but weve already determined the reason i couldnt copy it was because my hard drive is FAT32 and thy have a 4gb or something limit sooo i tried to convert to NTFS and as the previous message said "ok it said it couldnt convert and would i like it to do so when the computer reboots.. i clicked yes then restarted then the oc ran checkdsk then teh conversion started determining free space or w/e then it said conversion failed.. i didnt catch why as it flashed across the screen too fast then windows started up like normal... i have well over 300gb free space so that cant be the reason... any idea why i cant convert?"
