Playback PrBoom+ demo?

I know this question has probably been asked several times, and I believe I have asked this myself years ago. I just cant seem to find it in the forums.

I have the .bat for recording, I just don't have one for playing back my recorded demo. What must I put in the playback's bat file?

prboom-plus.exe -playdemo demoname

Playback is simpler. Just click on the demo to open it with Prboom-plus (the first time you do this, you might need to choose prboom-plus as the exe to open lmp files).
