Hi rx4age,
That is not a '
relative' path which you have provided - that is an '
absolute' path.
(
This M3U Wikipedia link will show examples)
Where is the M3U file saved in relation to the mp3?
I will be able to provide a relative path for you if I have that full path of the M3U file.
Once you include that path you cannot move either the MP3 or the M3U as the paths will then no longer be valid, hence the error being reported: "File does not exist" (...on the path specified).
