Short Filenames on NTFS Partitions (Windows NT/2000/XP) Popular

Open your registry and find the key below.

Create a new DWORD value, or modify the existing value, called "NtfsDisable8dot3NameCreation" and set it to "1" to disable 8.3 name creation.

Restart Windows for the change to take effect.

Note: Some installation programs may have problems with this option enabled, you can either re-enabled 8.3 creation during the install or use directory names in the short format i.e. "c:\progra~1\applic~1".
