- Google Chrome - Temporary files, history, cookies, download history, form history.
- Opera - Temporary files, history, cookies.
- Safari - Temporary files, history, cookies, form history.
- Windows - Recycle Bin, Recent Documents, Temporary files and Log files.
- Registry Cleaner - Advanced features to remove unused and old registry entries.

Changes in this new version:
- Added Chrome Canary Omnibox search shortcut cleaning.
- Added option to only clean Recycle Bin files deleted more than 24 hours ago.

It's perfect. You can mention it in the tutorial: How to Get Extra FREE Space in Windows?

I use this on a daily basis and it works well. It can even delete older System Restore points freeing up space (be careful though).

CCEnhancer
thewebatom.net/software/ccenhancer/
CCEnhancer adds support for more than 500 programs to CCleaner. It adds rules and definitions sourced from the Piriform Support Forum and other online resources to CCleaner's built-in WinApp2.ini system. When you run CCleaner again, the new programs are automatically included and ready to be selected for scanning.
However you can directly download the winapp2.ini file here:
content.thewebatom.net/files/winapp2.ini
Then, move the file to the path of CCleaner setup (by default, it is "C:\Program Files\CCleaner").
That's all. Run CCleaner and enjoy.
The extra selections (have an asterisk (*) at end) are disable by default.
CCleaner + CCEnhancer is pwned!!!

I just wondered that if i run Drive Wiper in my CCleaner and if i choose Free Space Only does it leave all my files in my hard drive and only wipes free space?? And will it empty my MFT too?? Does it leave all my files in my hard drive though i run it??
