Playlist (.m3u) and fully qualified file names

[Budgie]

I have a number of .m3u playlists which I created years ago and which have each track defined as a fully qualified file name. Trouble is the music data files have all been moved onto NAS and the paths from root have all changed. The manual states that minimserver recognises .m3u files as playlists but the ones I have do not work which comes as no surprise, I believe because of the changed path.

Does anybody have any suggestions as to the easiest way to edit the .m3u files so that they work on the NAS with minimserver. Does each track have to have the fully qualified file name which exists on the NAS or can minimserver build what is needed and if so how do I set this up?

Grateful for some help on this please.
