Disable 8.3 Filename Generation

article #978, updated 265 days ago

If your software is all new, let’s say 2013 and after, it probably makes sense to disable 8.3 filename generation, for a nice kick of speed.

To do it once for all drives, just do this:

fsutil behavior set Disable8dot3 1

If you want to do it for one select drive, say E:, first do a registry edit in

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem

you’ll want to change NtfsDisable8dot3NameCreation to 2. Then you will need to reboot, and in an administrative command prompt:

fsutil behavior set E: 1

and reboot again, and it’s done.
