## NAME
       ntfscmp - compare two NTFS filesystems and tell the differences

## SYNOPSIS
       **ntfscmp** [_OPTIONS_] _DEVICE1_ _DEVICE2_

## DESCRIPTION
       The  **ntfscmp** program makes a comparison between two NTFS filesystems from all aspects and re‐
       ports all variances it finds.  The filesystems can be on block devices or images files.  Ntf‐
       scmp  can  be used for volume verification however its primary purpose was to be an efficient
       development tool, used to quickly locate, identify and check the correctness of the  metadata
       changes made to NTFS.

       If one is interested only in the NTFS metadata changes then it could be useful to compare the
       metadata images created by using the --metadata option of [**ntfsclone**(8)](https://www.chedong.com/phpMan.php/man/ntfsclone/8/markdown) to eliminate the  usu‐
       ally uninteresting timestamp changes.

       The terse output of **ntfscmp** is intentional because the provided information is enough in each
       case to determine the exact differences. This can be achieved, for instance, if one  compares
       the verbose outputs of [**ntfsinfo**(8)](https://www.chedong.com/phpMan.php/man/ntfsinfo/8/markdown) for each reported inodes by the [**diff**(1)](https://www.chedong.com/phpMan.php/man/diff/1/markdown) utility.
