This is a very fast and great program to undelete files for Windows. It’s powered by a nice wizard (easy even for the average user) and it simply make the job. You can easily recover photos from a formatted SD/CF card.
Plus: the base version is also free.
Surely you can find other solutions for undeleting files, but this one is quick and free. As always Your Mileage May Vary, but I’ll use this software again 😉
