You just need to select a file from some directory using the menu similar to Midnight Commander, and MOC will start playing all files in this directory beginning from the chosen file. There is no need to create play lists like in other players.
If you want to combine some files from one or few directories on one play list, you can do this. The play list will be remembered between runs or you can save it as an m3u file to load it whenever you want.
In console type in “mocp” to fire up MOC.
