It was originally intended to recover lost partitions and fix boot issues, but its developers have gradually turned it into the multi-purpose file recovery software it is today.ĭespite being completely free, TestDisk supports most file formats and file systems, including FAT16 and FAT32, exFAT, NTFS, HFS, HFS+, ext2/3/4, LVM and LVM2, ReiserFS, and others.
It runs on many operating systems, including the newest versions of macOS (the users of macOS Catalina can install TestDisk via Homebrew, but there are some known issues). TestDisk is an open-source, freeware file recovery software application licensed under the terms of the GNU General Public License.
