A defragger is generally not needed in Linux due to the design of the
filesystems.

Actually that's at boot time.  If a program is "well behaved", it should
put temporary files in /tmp which is purged at boot time.  There are
other temporary files (the web browser's cache and such) which are often
in non-standard locations.

The "find" command can help you locate older files:

	find / -daystart -atime +5 -print

will find any file that hasn't been accessed in the last 5 days.  What
you do with such files is up to you.
