How to 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.
