Ive just done a test with WhatSize as my machine is getting full... G4 laptop OSX 10.3.9 - and theres a HUGE 54.1GB sparseimage...

excuse my ignorance but
1 - what is it?
2 - do I need it?
3 - can I delete it and get some memory back?

sorry if this has been done before - Im new here and my head hurts!
