    I was looking through my shell extentions and found one I don't understand. Well there are several I don't understand but most I can determine to be valid by the program its associated with.

    This one is an unknown shell extention. It has a command as 'Openas'. The program associated with it is "C:\Windows\Rundll32.exe Shell32.dll.Openas_Rundll%1 "

    Will someone explain this? Thanks.

    In Photoshop there is a file command 'Open As' - may well be associated with that or a similar program.

    Quote from PS Help -

    " To specify the file format in which to open a file (Photoshop):

    Do one of the following:

    (Windows) Choose File > Open As, and select the file you want to open. Then choose the desired format from the Open As pop-up menu, and click Open "

    "Rundll32.exe Shell32.dll.Openas_Rundll%1" is a perfectly normal registry entry, which associates particular file type with a program, which will open that file

    Hi PeteC and Broni

    I pretty much figured it was valid but I didn't understand the language or the association.

    Thanks for your replies.

    It is, in fact, used for opening unknown files.

    Your typing, dopey, leaves a tad to be desired.:rolleyes: :D

    There should be a comma twix Shell32.dll and OpenAs.

    Case sensitivity rules here as well: OpenAs_RunDLL.

    Stick the command into your run dialog box and replace %1 with c:\dopey.txt, for example, and see what happens. c:\dopey.txt must exist, of course, so create one.

    dopey--Quit mucking around your Registry. :D (See my response to your enquiry on .z.)

    Lots of mysteries in the Registry. I only play with it when I have a problem.
    But here are some tutorials for the Win98 Registry.

    The only problem is that by the time you even come close to understanding it, you will have WinXP, and the Registry for that is different.
