Make sure you have WSL with the Windows 10 Fall Creators Update installed. Ranger uses rifle as a file handler
and you need its config file, rifle.conf. If you dont have it (should be in ~/.config/ranger/rifle.conf), run
the command ranger --copy-config=rifle, then edit the resulting file.
To run Windows applications from Ranger, we will use cmd.exe /C start "" <file>, which works after the Fall
Creators Update. The problem is that Ranger will feed in file paths using Unix pathing, but start expects Windows
pathing. We will solve this by using sed to translate the path.
Add below code to your rifle.conf and you will be able to run Windows applications for the chosen file extensions.
