Crucial SSD utility reports


source

My crucial SSD utility reported that I should optimize my SSD performance by disabling 8.3 file name creation on all NTFS partitions. 

The use of 8.3 file names and directories for all long file names and directories on NTFS partitions may decrease directory enumeration performance. An 8.3-compliant file name refers to MS-DOS file-naming conventions. These conventions restrict file names to eight characters and optional extensions to three characters.

This article describes a method of disabling 8.3 file name creation on all NTFS partitions. 

Note: Although disabling 8.3 file name creation increases file performance under Windows, some applications (16-bit, 32-bit, or 64-bit) may not be able to find files and directories that have long file names.


Windows Vista, Windows Server 2008, Windows 7, Windows Server 2008 R2, Windows 8, and Windows Server 2012

To disable 8.3 name creation on all NTFS partitions, type fsutil.exe behavior set disable8dot3 1 at an elevated command prompt, and then press Enter.

This operation takes effect immediately (no restart required).

Notes 
When a volume is not specified, the operation updates the registry value:

  • 0 - Enable 8dot3 name creation on all volumes on the system
  • 1 - Disable 8dot3 name creation on all volumes on the system
  • 2 - Set 8dot3 name creation on a per volume basis
  • 3 - Disable 8dot3 name creation on all volumes except the system volume
When a volume is specified, the operation updates the individual volume's on disk flag. This operation is meaningful only if the registry value is set to 2.
  • 0 - Enable 8dot3 name creation on this volume
  • 1 - Disable 8dot3 name creation on this volume
