How to find the Target *.exe file of *.appref-ms

Question

I have to make a Backup of the Program running from the file *.appref-ms
When i Opened the File GitHub.appref-ms using text editor i found

http://github-windows.s3.amazonaws.com/GitHub.application#GitHub.application, Culture=neutral, PublicKeyToken=8f45a2159c87c850, processorArchitecture=x86

Where is the Target Pointing in the LocalDisk,
Editing the PublicKeyToken Resulted in Default or Null Icon.
Editing the URL Resulted in "Application Cannot Start".
How is *.appref-ms Targeting the Exe???
This doesn't answer my Question

Note : I tried Opening the File Offline, Still it Works Perfectly.

Simple answer to this; I was trying to figure out the same thing, and it just hit me.

GitHub IS a program installed on your computer, and when it runs, it WILL use threads and RAM. So that makes it a process. All you have to do is open Task Manager, click the Processes tab, find 'Github.exe', right click, Open File Location. Voila! Mine is in some App folder in Local, about 4 layers deep.
