I have my file type .unitypackage e.g. something.unitypackage.
And I want to run the command "E:\Unity\2018.2.1f1\Editor\Unity.exe" -openfile "%1" whenever the something.unitypackage is executed (by Enter or double-click).
How do I achieve this?
It seems like "Opens with" doesn't allow specifying options for my command, so if I just choose Unity.exe to open with, it won't do -openfile "%1" option.
