File size limitation of my flash drive

Hello all, I have a 8GB flash drive working all well apart from I'm not able to write any single file of over 4GB in size on it. I think it is because of FAT 32 formation of my flash drive. I'm using windows XP SP3 NTFS format and unable to convert flash drive's formation to NTFS from FAT 32. What can I do to overcome this bottleneck of file size of under 4GB.

Ya, it's coz of FAT 32 limitation. If you can't format with ur PC(Windows XP) - take it to a friend who has Vista, and format it as NTFS.


Ever wondered why you can’t format your USB drives to NTFS. Its because Windows XP by default won’t allow you to do so except format either to FAT or FAT32. But its fairly easy to get over it and enable NTFS files system on your removable devices.

NTFS does allow you encrypt your files with Windows XP’s built in file encryption. It also lets you to add allow and deny permissions on individual files and folders for specific Windows users, something you can’t think of using FAT systems. On the down side NTFS file system won’t get detected in most linux systems, besides that the encryption is pretty much useless. However if you can get over this few demerits NTFS file system is very good for daily usage.
