Windows 10: Why is "Open with..." context menu list missing one some file types?

I am curious. I am on windows 10 20h2. There are some file types that have "Open with" context list (like .mp3 or .jpg files) but with others, such as .zip files there is only a "Open with" button but not a context list. For those with only a Open with button, it brings up the "How do you want to open this file?" dialogue window. How do I add a context menu list to file types that only have a "Open with" button?

For example, for the .zip files I have other programs such as 7zip, comic reader and other programs that should file associate with .zip files. There should be a "Open with" context menu list that is the same in my old Windows 7 OS.

Custom context menu entries

So, just throwing this out there, in case somone knows.

I have added a custom context menu entry for the program rightload, since by default the menu is broken in vistax64.

It works pefect with single files, but when I select mutiple files and try to open, I get mutiple instances of the program (which makes sense), here is my entry:

C:\Program Files (x86)\Rightload\Rightload.exe --server=1 --autostart %1

So the %1 passes the filename to the program, and when I select multiple files it is just opening multiple instances of rightload each with a different file.

What I'd like to do is be able to pass a list of the files selected to the program. Since I know it is capable of uploading multiple files from the context menu, all in one instance.

So, is there something I can pass besides %1 that will do this? I have looked around and can't seem to find an answer anywhere... *Frown

 

How to fix 'Open with' on file context menu.

Only if things are working correctly. Here's a few things I notice:

1. When I go into 'Default Programs' and change .txt files to use another program I do get a list of other programs that I can use to open the .txt file. This list is what should appear on the 'Open with' context menu in File Manager.

2. The extensions with the 'Open with' problem also don't have 'Open' on the context menu. It should be the first entry on the list. I can still click on the file and it will open with he default program.

Got to be something in the Registry. I thought I would find under .txt in the Registry an Openwith List with wordpad and notepad. But there isn't any even on my VM Windows where 'Open with' works fine.

 

Add option to context menu to open file type

By default, Windows will open a MIDI file with Windows Media Player on double-click. This is fine. However, I'd like to add the option to open MIDI files to the context menu (right click).

As it is, to open a MIDI file with MuseScore (my current preferred software), I have to do: Right click > Open With > Choose Another App > More apps > (scroll to find MuseScore) > OK.

This is too many steps. How can I get the context menu to offer MuseScore as an option in it's menu - or at least as an option in "Open With"?

Thanks!
