Windows 10: Unable to associate extensions/file types with BAT scripts

Using the assoc and ftype commands, I was always been able to associate certain extensions/filetypes with certain Batch scripts. But, this didn't appear to be be working in Windows 10.

The following commands (run in a Admin command prompt) work fine in Windows 8.1 but not Windows 10:
Code: assoc .foo=Foobar ftype Foobar=C:\WINDOWS\system32\foo.bat %1 echo @echo off > foo.bat echo echo The filename is %1>> foo.bat echo hi > foo.foo foo.foo[/quote]

The result should be the output:
Code: The filename is C:\WINDOWS\system32\foo.foo[/quote] Windows 10 appears to do nothing, but then I thought of changing the foo.bat script to redirect to a log file, so foo.bat now looks like this:
Code: @echo off echo The filename is %1 > foo.log[/quote] When running foo.foo, foo.log is created, so we know that the file association (.foo files associated to foo.bat) is working and foo.bat is running. It's just that there's no output in the DOS window.

Also, adding a "pause" command at the end of foo.bat does NOT pause at all, so this shows that input and output are both broken/redirected.

What could be causing this input/output redirection? Remember, it only happens when running the foo.foo file directly. If you run "foo.bat foo.foo", it's fine.

Thanks!

File associations in Windows 10 not working

Many of my file extensions are not pointing to the programs I need them to point. For example I create script files that are used by AutoCAD. The script file has an extension of .scr that I use a text editor program like Notepad to create it. When I upgraded
to Windows 10 the .scr extension was set to open using the AutoCAD Script Editor. I tried to change the default program using a right click "Open With". However the "Open With" option was not available for this file type. I then tried: Right click on Start
> Control Panel > Programs > Default Programs > Associate a file type or protocol with a program. I clicked on the .scr extension, clicked "Change Program" and it would not change. The only way I could get the file association to not be "AutoCAD Script Editor"
was to Right click on Start > Run > regedit and delete all occurrences of the key .scr. After this I was able right click on the file and use "Open" to associate the file to Notepad. This worked, however, I think I'm missing a step. The "Open with" option
is not available when I right click the file, like it is for other files. I would like to know what step I missed to get "Open with in the right click options.

Also, many of the file extensions indicate "Unknown application" so I suspect this issue may be affecting over 350 file extensions. Does Microsoft have a fix to fix all these "Unknown application" issues?

 

I have problem unassociating files in Win10, specifically WMP.

Hi Bruce, it is hard in Windows to break file associations . . .

Open File Explorer

On the View Ribbon, check the box marked 'File Name Extensions' - so you can see the extension on a file

On your Desktop, create a dummy file with a .bat or .exe file extension

(Basically right click Desktop, choose New - Text document and change the file extension from .txt to .bat or .exe)

Right click any zip file, choose open with - Choose another App

Check the box marked 'Always use this app to open zip files' - IMPORTANT!

Scroll to the bottom and click 'More Apps'

Again scroll to the bottom and choose 'Find another app on this PC'

Navigate to the dummy file on your Desktop

The zip file will not open

Delete the dummy file on your Desktop and restart your PC

The file association will then be broken!

 

Looks like Microsoft changed the polarity of a setting in the registry for Windows 10, and there's a simple fix for it.
