How do I clean up MATE open with?

[ToddAndMargo]

Hi All,

I created a qemu-kvm virtual machine from
    Fedora-MATE_Compiz-Live-x86_64-39-1.5.iso
so I could run an app in wine 9.1.

How do I clean up my MATE "Open With"?

Here is what it looks like:

Many thanks,

Have you done something like set options to open mimetype
application/octet (basically every miscellaneous binary file) with
something?

Mate has a control panel for "preferred applications," but it only
configures a few different groups of file types.

I'm not sure about bruteforce resetting control over a lot of different
mimetypes.  My first thought was to look for config files related to
mimetypes.

e.g. locate -i mime | grep /home

There's an xdg-open tool that used to be used as a file handler by
various things, I'm not sure if it still is.  Nor can I recall how it's
configured, but it might give you a research hint.

You may be fighting a losing battle if there's some app that decides it
should be able to open just about every file type, and other apps with
the same mindset.

I'm still glad that on Linux is reasonably safe to double-click almost
any file I've saved to open it / view it / read it, and not have to
worry about executing it.  Though I still right-click on things I have
little clue about what they are, to open them in some benign app.
