Is it possible to defrag the hard disk without admin rights?

I'm using Windows XP.

Best Answer

Short: No.

Long: You can't because it requires rearranging the filesystem, which is dangerous because a virus defragger could rearrange the filesystem and then with a single block change, it could replace a vital program with its own version.
