Disable 8.3 Name Creation in NTFS

Files that use the 8.3 naming convention can degrade NTFS drive performance. Unless you have a good reason for keeping the 8.3 naming convention intact, such as using 16 bit programs, a performance gain can be achieved by disabling it as follows:


[Start] --> [Run] --> Type Regedit --> Press Enter --> then Navigate to following key.


Registry Key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem



Modify/Create the Value Data Type(s) and Value Name(s) as detailed below.



Data Type: Dword // Value Name: NtfsDisable8dot3NameCreation
Setting for Value Data: [0 = Enabled / 1 = Disabled]



Exit Registry and Reboot
