TestDisk is a free Windows tool for two situations: a partition has vanished, or a disk will no longer boot. Version 7.3 from CGSecurity came out on November 29, 2025. The file is fetched from the developer's own server at www.cgsecurity.org.
Who needs a partition recovery tool like this
TestDisk deals with damaged or missing disk structure. CGSecurity describes it as software that recovers lost partitions and makes non-booting disks bootable again. It suits an unreadable drive better than the case of one deleted photo.
It costs nothing and is released under GPL-2.0-or-later. The package is about 28.9 MB. Disk Drill, Recuva and Wise Data Recovery are alternatives if file-level recovery is what you need.
What the 28.9 MB package does in practice
The package is 28.9 MB and its functions are partition recovery and boot repair. Anything beyond those two jobs is not confirmed.
Check the official site for usage details before you start.
Limits and alternatives to compare
File-level undelete is not part of this app.
If your need is different, alternatives include Disk Drill, Recuva and Wise Data Recovery.
