Recently I am getting disk full messages when performing the simplest of functions with my HP scanner. I delete a bit to gain storage space back but quickly the message comes back after I scan a few docs. So I surmised that it's a temp folder somewhere and sure enough there is 11GB hiding out here: /private/var/folders/rs/5n3rrgc13zn2znxfx96xmq0h0000gn/T/TemporaryItems (10.89 GB on disk) for 398 items Every single file is named "hpf TMP" so this is obviously the culprit. Why does the scanner do this? There are no settings to prevent temp files. I'll just delete all of them except of today's.
