I did Reinstall Windows a while ago, but I forgot to backup some specific files (Some iPod Touch Applications, which is what I REALLY need), And I don't know how to restore them, I tried the programs: Data Recovery, Recover My Files and TuneUp Utillities 2011 and none of them worked, any way to restore them?
Doubtful, when you installed Windows it overwrote some of the data, the longer you use windows the more data it will overwrite, overwritten data is Unrecoverable by any means.
What old data is left might be able to be recovered by Get Data Back
You should not install this software on the hard drive you are trying to recover, attach the hard drive to another PC and run the recovery software from there. I doubt you will recover much of your old data.
There are to important factors:
A good (but expensive) software is Ontracks Easy Recovery.
