Deleted by bypassing the Recycle Bin or after emptying it;
Lost due to a virus attack, system crash, or power failure;
From failing disks. R-Undelete can image such disks to recover lost files directly from those images saving the disks from excessive loads;
From deleted, damaged, formatted disks, or even more, from partitions with unsupported file systems. R-Undelete scans hard drives to find those disks and partitions. If the previous partitions are very severely damaged, R-Undelete can find files using raw file search, that is, by searching for file signatures.
