Accidentally deleted an important file? Lost something important when your computer crashed? No problem!
Recuva is a data recovery program for Windows, developed by Piriform. It is able to recover files that have been “permanently” deleted and marked by the operating system as free space. The program can also be used to recover files deleted from USB flash drives, memory cards, or MP3 players
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. As of version 1.5.1 it can also recover files from Ext2 and Ext3 file systems.
As with other file recovery programs Recuva works by looking for unreferenced data, but if the operating system has written new data over a deleted file then recovery will often not be possible.
