When I look at files in the Windows-8.1 file explorer, I can right-click a file and select "Open With" to choose a program that allows me to open that file. For instance: when I select a PDF file, I can choose Adobe Acrobat, Adobe Reader, some MS PDF viewer and Firefox.
I do no want to change the default program (which is Acrobat in my case), but I want to add another program I've written myself and that allows me to inspect the PDF syntax.
Currently, I need to use "Choose default program...", uncheck "Use this app for all .pdf file" and than select that specific program in "More options." That involves quite some clicks and I would like the program of my choice to show up as the second or third item in the list that is provided when I click on "Open with..."
I've Googled around, but all answers refer to something called "Group Policy Management Console" which is apparently something that is available on Windows Server and that allows administrators to configure policies for multiple users. I'm a single user on a single PC; I don't think I have (access to) this "Group Policy Management Console" (I can't find it).
Is there another way to expand the list of apps when I click on "Open with..."?
