USB Drive question

[FizWizz]

Alright, I don't know a whole lot about Windows' file systems so if I make a blunder here or there, I'd be more than glad to be corrected.
I have a 2Gb Flash drive and I wanted to know this: currently it uses the FAT32 file system, and I wanted to know if I would get much more space by reformatting it to NTFS, which as I understand it, makes better use of disc space in one way or another. I haven't done it yet because I know that it also has system files on it, and I don't know if/how I can preserve these files through the reformatting process. Any help here would be appreciated..

Most flashdrives don't like NTFS. Besides, using NTFS causes more writes to the drives, and since flash drives have a limited number of times each area can be written to, you'd be killing the drive faster.

NTFS technically makes better use of diskspace, but practically it instantly sections off 15% of whatever partition you apply it to so it's pretty useless for it's compression abilites.

Alright then, I guess I should be happy with what I've got.

Also note that using NTFS means you need to enable delayed write caching so you cant just unplug your drive straight out anymore either.
