Within the editor .vbs files have the appropriate syntax highlights but it seems it doesn't appear in the file viewer.

Here is my gist so you can use it for testing if it helps.

Just adds a toggle for hidden files to the context menu for easier access because I disabled the Explorer ribbon.

The first file is a .reg, I believe gist doesn't have support for registry files so I sent a request for it (idk if it will go through, I'm unaware of any reasons i.e. security implications perhaps for lack of support). I changed it to .txt because otherwise it gets marked as "#Other" in the language tab.
