m3u rotation

[kenb]

Our school is using radiodj, and everything is working fine.
Station set up: dedicated computer with 3 hard drives, win 7 pro. Using juice and Butt.
The song files are on one dedicated drive, with songs in separate folders according to genre.
some files have over a hundred songs each. we use Mixtape to create m3u files. songs play in events
with no problem.
Question: is there a way to create a category in track manager so each genre will have its own category
so the m3u can be rotated by the rule "least played m3u file? I have created m3u categories by genre, but
when trying to import folder, radiodj does not find any m3u files.
Thanks

9/21/2017 I have read all of DJ-jHONNY's tutorials about play list, m3u etc, but when I try, it does not work. I am
wondering if I need to re-install radiodj??!! I get to the point of importing folder and it says please wait, forever..

I have restarted computer, ran virus scan, registry cleaner, restarted radiodj, and symptoms remain. I created new category, with sub-category, and tried to import m3u, but nothing imports. I trid to import track, but can not fill in path/URL. Please help. I am sure it is simple but brain is getting information overload from reading every post I can find.

O.K. I finally get it. I reread notes by Marius and the answer is very plain if you follow the steps he outlines. I admit to  a very hard head...
