I recently download a app called DustBuster and i first ran cclceaner then ran dustbuster and dustbuster still removed over 600Mb of junk. Now as we are getting close to version 2 i thought it would be great for CCleaner to scan your pc for selected junk files and the ability to add your own junk file extensions. Here's hoping
"DustBuster is a garbage file removing utility for Microsoft Windows operating systems. It searches for junk files and temp files that are of no use and are just taking space on your hard drive. Based on a "common sense" scanning technology, DustBuster now cleans over 1500 different types of useless temp files and directories in a single click, detecting and deleting all these unneeded files automatically."
