Pass command line arguments with file links

[b.ca...@gmail.com]

I can't seem to add arguments to a "file:" link. Win10 Pro returns file not found error. The link works when running only the target application but as soon as I add %20 and the argument I get that error message. For example file:C:\Program%20Files%20(x86)\Mozilla%20Firefox\firefox.exe works but file:C:\Program%20Files%20(x86)\Mozilla%20Firefox\firefox.exe%20https://www.mylifeorganized.net does not. How is this done?
