Un-Associating a Filetype

[Thom Slack]

In NT 4.0 I have some filetypes (ex: config.000) that are associated with
Notepad. They got this way by double-clicking on the file in Explorer,
and having the "use this application every time" box checked when using
Notepad to check the file.

I would like to break this association, but the file extension (.000) does
not show up on my Flie Types list under Settings.

Is there any way to do this? Is it in the user or machine profile (we use
central profiles on our network for the users)?

Thanks.

you need to go to HKEY CLASSES ROOT in the Registry, and find an "Auto_File"
type (in the bottom half of the hive: the top half lists extensions in
order; the bottom half lists File Types). I guess in this case it would be
"000_auto_file". Just select the auto file type you don't want
(000_auto_file), and delete the whole thing subkey.

(you can also search the keys for "auto_file" to find all the auto_file
types you have listed from doing that automatic association garbage)

Too bad MS didn't make this easier for the 99.99% of the people
that have been warned, and obey the order not to edit the resistry.

Could this be used to ADD an association? I frequently get files with no
extension, like README, and I have to open up a text editor, change
directories etc. to get to it. As best I have been able to tell, there is
no normal way to get the system to default to my editor if there is no
extension.

Anyone know how to do this?

Thanks!

I had the problem of NT not letting me add a type, with some message relating to "xxx_auto_file" already
using the type. To get around this, I cleared the .xxx association at the cmd prompt with syntax "assoc
.xxx=" minus quote marks, then did the add steps with Explorer. It seemed to work okay.
If there's something wrong with this I'd be grateful of a heads-up.

my solution was to put a shortcut to my text editor in the Send To folder so
I can "send" any file to the editor:

make a shortcut of your editor; put it in "c:\winnt\profiles\{user
name}\send to"

There is another way, if you don't want to mess with the Registry.

Try using this command in a DOS window

ASSOC

So, if files like .xxx are accidentally associated with notepad, try
this to de-associated them:

ASSOC .xxx=

This is similar to the SET command where if you do a SET VAR= the
definition of VAR is un-defined (VAR is removed).

Try putting ASSOC in the NT Help Find field and navigate to that topic
for a full explanation.
