In Windows 8 when using the Windows 7 File Recovery tool to restore files to an alternate drive you may receive an error that says, “A file cannot be restored. Error: Short names are not enabled on this volume (0x80070131).”

In Windows 8 all drives other than C have 8.3 name creation disabled. You can verify this by running the following commands from an elevated command prompt:

fsutil behavior query disable8dot3 c:

fsutil behavior query disable8dot3 e:

Notice that 8dot3 is enabled on the C drive but disabled on the E drive. To enable 8dot3 on the E drive running the following command from an elevated command prompt:

fsutil 8dot3name set e: 0

Now attempt the restore again & you should not receive the error.
