Does anyone know any software to recover deleted files?

[famana66]

Hi, I have a small problem for which I would like you people to help me out. I have been using my system since a few years which runs XP on it. A few days back ,I had been out and during that time my kids deleted some important video files and databases that are now required. To have more troubles I have re-installed windows on that and now I need the deleted ones back. So, I am looking for a software that can be the best resort to my problem.

Please help me out in getting one!!!!
