Display File Extension on Unknown File Types

Hello

I dont know if Im on the right section to post this.

I just want to ask to our fellow members and gurus here, I dont know what went wrong but suddenly the unknown file types in my Windows 7 PRO x64bit doesnt display its file extensions anymore..

How can i restore it to default? to display the file extensions on unknow file types in windows 7...

Any tips would be much appreciated. Thank you..

Windows Explorer/Organise/Folder & Search Options/View.

You should find it in there. (that's "hide extentions for know file types") Might be what you need.

I already checked the hide extensions for known file types, and the unknown file types hides its extension also...

Note: this is not only on one specific file types but all unknown file types hides its extention file types also..

Okay, I managed to find a solution for this. I dont know if this is the Windows 7 Default but it fixes my problem on unknown file types to display its extention..

I just go to registry editor;

navigate to:

HKEY_CLASSES_ROOT > Unknown

add new String with the name AlwaysShowExt
then restarted explorer...

I would like to know the right registry for the Unknown key in Windows 7 Default Registry entry (and would be great if someone can upload the .reg file of it)
Thanks.

You're most welcome.

I was just referencing that tutorial in case you wanted to view and/or check the registry entries for it.
