In computing, recover is a primitive file system error recovery utility[1] included in MS-DOS / IBM PC DOS versions prior to DOS 6.0[2] and a number of other operating systems.
Overview
Typing recover at the DOS
disk partition was hopelessly corrupted, but that the FAT and non-directory areas might still contain useful information (though there might be additional bad disk sectors
not recorded in the FAT).
The program removed all subdirectories and all entries in the
undelete utility.[3]
In DOS version 5, another mode of operation was added: specifying a single filename on the command line would cause the program to test all the disk sectors used to store the file, and shorten the file by omitting sectors which tested bad.[4]
DR DOS 6.0 includes an implementation of the
recover command.[5] The command is also available on SISNE plus[6] and IBM OS/2.[7] The FreeDOS version was developed by Imre Leber and is licensed under the GPL.[8]See also
