Hi sams20,
looking at file dates/content before deleting them is of course OK. If you are in doubt whether some user might need their data, you could move it temporarily away, let's say to /var/tmp and wait what happens.
Without having got any feedback after several days (weeks?) from your users, you could finally delete the files. From my experience, most users won't even remember they once put something into /tmp.
One more hint - do you have a directory /tmp/ibmsupt with data in it? This directory is used for gathering system information (via 'snap' command) to be used by IBM support people. If you don't have an actual case with IBM, delete the contents of /tmp/ibmsupt using the command 'snap -r' - and delete 'core' files, if any.
480 MB is not _that_ big, but should be enough for most systems.
omarfarid - under AIX /tmp does not get emptied at reboot, as is the case under e. g. Solaris.
