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. Follow steps below :

1. Go to Registry Editor (Run then type regedit and press Enter).
2. Find key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem\
3. On right panel choose NtfsDisable8dot3NameCreation, double click and change value to 1.
4. Exit the Registry Editor and reboot.
