CCleaner <--> ClearProg

Hello,

I was used to use ClearProg but found CCleaner some days ago.

I compared both programs and found some things which CCleaner seems not to delete:

Internet Explorer

Delete AutoComplete-Entries in Webforms

Opera

Cookies

Typed URLs

Donwload List

Netscape/Mozilla

Typed URLs + Last page

Windows

Windows Temp-Filder

Clear System-Temp

Open/Save Filelist

File Searchlist

Computer Searchlist

Networkdrive list

LastKey (Regedit)

Clipoard

There is also no way to do a "Secure delete" (overwrite 12 times with random code).

What about these things. Does CCleaner delete them or are there any hidden features?

Just tried that "ClearProg" application and it found 13.8 more megabytes than Crap Cleaner !
