Disable 8.3 File Naming

By default, Windows XP stores filenames in two formats, Long filenames and 8.3.
Long filenames are what you normally see in Windows and can have up to 255 characters. 8.3 is an older system that uses up to 8 characters for the file name, and 3 characters for the extension, ie. letter.doc. Unless you plan on running some applications that are pre Windows 95, there is no need for this extra burden on the filesystem.

To disable the 8.3 filesystem, Open REGEDIT and navigate to:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\FileSystem
Locate, or if it doesn't exist, create DWord NtfsDisable8dot3NameCreation and set its value to 1.

A word of caution, some programs still use 8.3 file names, such as antivirus applications.
