*temp includes any files that have the letters temp in their name - counld be conTEMPorary.doc for instance. This is NOT the search you want - it's the *.temp and *.tmp searches that are most likely to be correct.
But as I said before - this won't find all the files that can be deleted, as many of the ones you will see in the Temp folder are regular files, which are no longer needed (because of the failure of some software to clean up properly after use).
Common question and an easy solution. Bang them all in the recycle bin and wait until you have used the machine for a time that would cover all the progs installed. If theres no problem, empty the bin.
