Recuva (pronounced “re·cov·ah”) is a freeware Windows utility, developed by Piriform, to restore files that have been accidentally and “permanently” deleted from your computer.
Lost something important when your computer crashed? No problem! Recuva recovers files deleted from your Windows computer, Recycle Bin, digital camera card, or MP3 player.
Recuva was described by vnunet.com as an “effective tool for undeleting or salvaging files we sent for recycling and deleted, in the past”.
The program works on both FAT and NTFS file systems. It is able to recover lost directory structure and automatically renames files when trying to recover two files of the same name.
OS: Microsoft Windows 7, Vista, XP and 2000. Including both 32-bit and 64-bit versions.
