All of them or do you have a specific file type in mind?

Open Windows Explorer, click on TOOLS, and selct FOLDER OPTIONS

Select tab FILE TYPES

Then go down through the list, find the file and there it shows yoiu what
is associated with that file type

select REMOVE at the side, ignore MS's dire warning of great calamity, and
select ok.

When you go back to you list of files, it should show your icon changed,
and won't open with anything.

Watch out if indeed the file is something really basic, Windows gets a bit
quirky about being disrupted and may punish you.

Remove the Registry key. If the file extension is .xyz
then remove HKEY_CLASSES_ROOT\.xyz

The way it works is that Explorer looks under HKCR
for the file extension. The default value there then
points to another key. For instance, under HKCR\.txt
should be "txtfile".
The second key provides association information.
Under HKCR\txtfile\shell\open\command should be
something like C:\Windows\System32\Notepad %1

So you can change the association by changing
the HKCR\.txt default value and you can remove it
by deleting the HKCR\.txt key.

In a command shell (cmd.exe), run "assoc /?". If you don't specify the
filetype handler then whatever is currently assigned is removed.

As examples, run "assoc .txt" and "assoc .rtf". What you get back are
the filetypes define in the registry. You could use registed to see how
they're defined but I doubt you care since you just want to wipe
whatever is currently assigned.
 
Thanks all.

I tried to do it in Control Panel / Folders Options but Remove was
disabled ????

Anyway I changed the association to something not obnoxious (just a
term of endearment) and that was allowed (sorry it was late, but I
think I used .txt), then when I went back to Control Panel / Folder
Options; Remove was enabled so I clicked it and it then did remove the
association.

Any ideal why Remove was disabled?

It's prevented by the "EditFlags" value in the file type subkey.
See "Creating a File Association" and "FILETYPEATTRIBUTEFLAGS" articles on
MSDN.
 
I have associated .CLP ext to Clipbrd.exe and it does not work
in Windows XP and Windows Me.
I have tried quite a few time but no luck.
It opens the clipbrd.exe as blank but no contents of
.CLP file.
The .CLP association in the registry appears to be ok.

Any advice would be appreciated?

Your CLP file is probably not a valid NT/Win3.1 clipboard file, or is
corrupted.

Try putting something into the clipboard, open CLIPBRD.EXE, save the current
clipboard, close CLIPBRD.EXE, then double-click the newly saved CLP file.
 
When I "Save As" in the Clipbrd.exe and try to open it
by d/c, the answer is "Access Denied" or "Unknown Application"
where as before it use to open a blank clipbrd.exe screen.
I can delete the "Save As" .clp file easily.
There is no "Access Denied" restriction to delete the CLP file.

The fact that the result/error is inconsistent, it's likely caused by faulty
RAM or harddisk. Or damaged EXE due to malware/virus.

The registry defaults for .clp are here. The line with the "-"
in it, I think that removes the old key, while the three lines
below it define the default again. This should give you
a hint as to what needs to change (while you're looking in
RegEdit).

[*.clp] files, that have been saved with the application "ClipBook Viewer
[Clipboard]" (clipbrd.exe), can *only* be opened with the;

File > Open...

...menu function, from *within* that application - it does NOT support
opening of [*.clp] files by the parsing of a command line and appending it
with the filename.

I've no idea why this application does not support opening files from the
command-line, but the fact is that it does not...

It's because the application reads the last saved item from memory, it
would have to discard this buffer to open another file, I guess a
decision was made to have it keep the save buffer at all times rather
than permit it to open files and discard the last saved item.
