Recovering files erased from memory stick

I accidentally erased some files from a memory stick this week. Normally, when you delete files from your hard drive, they reside in the computer's Trash Can until you finally empty the trash. And before that, if you realise you still want them, you can restore the files from there. But files erased from a memory don't go to the Trash in the same way - they are gone. Well, not exactly. A good recovery utility can still get them back. So I tried the free program Recuva, and it did an excellent job. Some of the files were not recoverable, but 90%-95% were, so I'm, a happy chappy again. Incidentally, you can perform the same rescue operation from a digital camera. In both cases, make sure you save the recovered files to a different disk. The Piriform website is also the home of CCleaner, an indispensable anti-spyware utility, and some other goodies worth investigating.
