Pandora Recovery

Pandora Recovery is a powerful free tool that provides its users an effective way to attempt recovery of permanently deleted files.  Pandora Recovery actually recovers files permanently removed from Recycle Bin, files originally deleted using Shift + Delete keys bypassing Recycle Bin and files deleted from DOS prompt. Pandora Recovery is not a backup tool; it can recover files that have been deleted months before Pandora Recovery was installed. And while the likelihood of successful recovery is negatively affected by the time passed since the deletion of files, Pandora Recovery users were able to recover files deleted more than five years after deletion.
