NtfsDisable8dot3NameCreation=2

[laderio]

Hey,

i discovered that my Windows 7 RC x64 has a default value of 2 for the entry NtfsDisable8dot3NameCreation. I could not find this value in Microsoft Technet for Windows Vista or Server 2008 (only 0 or 1):

Has someone an idea what this value does?

Has someone an idea what this value does?

Try

fsutil behavior query disable8dot3

or in general fsutil and any help you can get on it.

(I don't have 7, so fsutil might be removed or renamed).

OK, he says in German:

Der Registrierungsstatus von "NtfsDisable8dot3NameCreation" ist die Standardeinstellung "2" (Volumeebeneneinstellung).

That means in English:

The registry status of "NtfsDisable8dot3NameCreation" is the standard setting "2" (Volumelevelsetting)

Seems, that you can adjust this per volume with windows 7.

About the new values for NtfsDisable8dot3NameCreation:

http://technet.micro...996(WS.10).aspx

Description

Specifies whether NTFS generates a short name in the 8.3 naming convention for long file names and for file names that contain characters from the extended character set. If the value of this entry is 0, then files can have two names: the name that the user specifies and the short name that NTFS generates. If the name that the user specifies conforms to the 8.3 naming convention, then NTFS does not generate a short name.

Changing this value does not change the file, but it does change the way that NTFS displays and manages the file. Also, files are named according to whatever rule is specified by this entry at the time of their creation; changing this entry does not alter the names of existing files.

-----------------------------------------------------

Value and Meaning

0 NTFS creates short file names. This setting enables applications that cannot process long file names and computers that use differentcode pages to find the files.

1 NTFS does not create short file names. Although this setting increases file performance, applications that cannot process long file names, and computers that use different code pages, might not be able to find the files.

2 NTFS sets the 8.3 naming convention creation on a per volume basis.

3 NTFS disables 8dot3 name creation on all volumes except the system volume.
