Safe to delete /private/var/tmp/*?

Question

In this folder, there are 14GB of archives with names such as WiFiDiagnostics follow by a date. Is it safe to delete these archives? A reboot did not remove them.

Answer 1

WiFiDiagnostics* sounds like something you can delete without impact. There are other things in /private/var/tmp which probably shouldn't get deleted (e.g. filesystemui.socket) so rm * is not advisable.
