This key stops the NTFS volume from generating MS-DOS compatible 8.3 file names. Disabling this feature can increase the performance on heavily used NTFS partitions that have large amount of files with long filenames.

Warning: Some 16 bit installation programs may have problems with this option enabled, you can either re-enabled 8.3 creation during the install or use directory names in the non LFN format i.e. "c:progra~1applic~1"
Key: [HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlFileSystem]
Value Name: NtfsDisable8dot3NameCreation
Data Type: REG_DWORD
Data: (0=disable, 1=enable)
