This setting controls whether MS-DOS compatible 8.3 file names should be generated on NTFS partitions. Disabling this feature can increase the performance on high usage partitions that have large amount of files with long filenames.

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".

		(Default)	REG_SZ	(value not set)
		NtfsDisable8dot3NameCreation	REG_DWORD	0x00000001 (1)

	HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem
