Do I want to know how you can specify a subtitle to a video file?

example:

potplayer.exe C:\video.mp4 C:\video.srt

in this case I can play the video.mp4 (with the subtitle) using only: potplayer.exe C:\video.srt

But i wanna do:

potplayer.exe C:\video.mp4 C:\File\1\2\3\subtitle.srt

The CmdLine.txt is not helping me.
