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 if you’re using 16-bit programs), a performance gain can be achieved by disabling it.

Set the Registry

DWORD key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem\NtfsDisable8dot3NameCreation to 1.

Exit the Registry and reboot.
