To disable the use of long file names and extended timestamps, allowing only the FAT file system features from Windows 3.1:
1. Open a CMD.EXE window.
2. Using REG.EXE, built into Windows XP, Windows Server 2003, and later operating systems, or installed from the Windows 2000 Support Tools, type:
REG ADD HKLM\SYSTEM\CurrentControlSet\Control\FileSystem /V Win31FileSystem /T REG_DWORD /F /D 1
3. Press Enter.
4. Shutdown and restart your computer.
