I need help for a „simple“ task 
I changed my NAS to a newer and faster (RAID) version and at once reorganized my own media library folders.
Now I have to modify all my Volumio playlists because the structure of „volume/root and folders“ changed, only the media file names are still the same as before.
I have 5 Volumio players for parents/kids/party/etc.
None of them is multiroom.
Each Volumio player has a lot of individual playlists.
All are using the same media library in common.
Is there a „standard solution“ for this individual issue?
Any help and/or idea is welcome
