I'm using only one nfo for my entire playlist (nfo.txt). It would be cool if I did not have to set the name of the nfo in the cmd.
Like I keep my nfo.txt (or *.nfo) in the directory and Prismedia know that the NFO is the same for all uploads.
If you do want to keep the .txt extension maybe look for the file with the same name as the folder :
Graveyard Keeper/ Graveyard Keeper.txt video1.jpg video1.mp4 video2.jpg ...
Since I put Prismedia and my videos in two different drives and Windows do not really help you in the terminal (or I know better the bash shortcuts maybe) typing as less as possible some paths on screen is always good :)
