Improve NTFS Performance

Modifying your registry can cause serious problems. Please make a restore point or export the keys affected by these registry files. The batch files export the registry keys for you and are placed in My Documents under RegBackup.

If you are not sure how to export or merge registry keys, I have written a quick tutorial.

This registry file increasses performance on NTFS drives by doing two things. It disables NTFS from generating MS-DOS compatible filenames for files with long filenames. It disables the time stamp that NTFS puts on directories whens they are accessed.

Some 16-bit applications might not function correctly without the truncated files names. To correct this, just merge the exported key or the undo patch provided below, and reinstall the application.

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\FileSystem]
"NtfsDisable8dot3NameCreation"=dword:00000001
"NtfsDisableLastAccessUpdate"=dword:00000001 

1. ImproveNTFSPerf.bat
2. ImproveNTFSPerf.reg
3. UNDO_ImproveNTFSPerf.reg

Save #1 to your desktop, double-click the batch file, the affected registry key will be exported for you, and the registry file will be merged. If you want to undo just merge the EXPORT_Filename.reg file.

Usually your computer must be restarted for these to take effect.
