Unfortunately, neither this (or any other) data recovery program will NOT be able to restore files that have been “multi-pass cleaned” by CCleaner, especially if you have deleted the files by using CCleaner’s “seven-pass” deletion. Not even U.S. Federal recovery techniques will be able to restore that data!
Simple deletion through a quick “emptying of the recycle bin” will be recoverable, though, and that’s what most people use (especially Yahoo! and AOL users), so those files will be recoverable!
