Disable the 8.3 filename creation process

Are you using the NTFS file system on your hard disk? If you've ever used the DIR command along with the /x parameter in a command prompt window, you've seen firsthand that Windows XP creates an 8.3 filename for each long filename that you create. The OS does this to maintain backwards compatibility with older 16-bit applications.

However, the process of creating and maintaining 8.3 filenames adds a lot of overhead that can significantly degrade the overall performance of the NTFS file system. Chances are good that you're not using any of these older 16-bit applications, so why suffer the performance hit?

Here's how to disable the 8.3 filename creation process:

1. Launch the Registry Editor (Regedit.exe).

2. Go to HKEY_LOCAL_MACHINE\System\CurrentControlSet\


3. Double-click the NtfsDisable8dot3NameCreation value.

4. Type 1 in the Value Data text box, and click OK.

5. Close the Registry Editor, and restart the computer.

Note: Editing the registry is risky, so be sure you have a verified backup before making any changes.
