Where do you type this stuff, I don't understand?

If I understood the question correctly,
can be entered and executed in cmd.
(ex: If you type "D: \ Program \ idle_master \ steam-idle.exe 54029" in cmd, in that path, "CS: GO" is idle)

run the command many times, with each appid after it? it should open multiple instances of steam-idle.

I tried it, but only the first game was idle.
Perhaps there is a turn in open multiple instances.
Please make sure my command is correct. ty

I already have a Trading Cards, but I want to fill steam playtime

I know and it was success.

But only idle one game.

I want to making idle many games (~50 games)
