If you are using Windows NT/2000/XP and have it set to use NTFS, a registry
value that determines whether NTFS generates a short file name in the 8.3
naming convention for each long file name must be set to 0. This setting is
the default setting when you install the operating system. If this registry
value is set to 1, NTFS will not create the short file name.
It is possible that this value could have been changed - either manually or
by a program..
To check the registry key and change it if necessary:
1. Click Start>Run.
2. Type regedit and then click OK.
3. Navigate to the following key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Filesystem
4. In the right hand pane, right-click the following value, and then click
Modify:
NtfsDisable8dot3NameCreation
5. Change the number in the Value data box to: 0
Please note that this is a DWORD value, not a String or Binary value.
6. Click OK.
7. Click Registry, and then click Exit.
Note you can save the registry key first by:
On the File menu, click Export.
In the File name box, type SaveKey, and then click Save.
Or create a system restore point prior to editing.
Note: If the registry key is not there, you can simply create one by going
edit > new.
