I ran CCleaner for about 12 hours on secure delete (35 passes) and when it completed I got the following:
CLEANING COMPLETE - (45388.815 secs)------------------------------------------------------------------------------------------
6,158,341,453,260.7MB removed.
Secure file deletion enabled - Gutmann (35 passes)
------------------------------------------------------------------------------------------
Details of files deleted
------------------------------------------------------------------------------------------
IE Temporary Internet Files (5113 files) 14,637,517,471,968.8MB
I bet Google would love to barrow some of my spare hard drive space... lol Anyway, I found it funny that the IE Temp files that got removed were twice as large as the total amount removed.. (Neither of which are anywhere near accurate.)
