Are you looking for a way to make crates that are mirrors of your folders?
What will happen when you add one new track to an old folder? Will you expect that to be automatically updated in the Crate as well?
I do things manually with any dj software.
i can have one track in multiple crates.
I think we all got used to the old Artist Folder > Album Folder way of doing things from itunes and windows media player organisation.
I do things differently now, I have two folders (Music and Video) each has about 10 folders of the broad genre description eg
HOUSE will have all forms of house from deep to tech
POP = Poppy stuff, Charts stuff
DANCE = Big Room, Club Dance
REGGAE = Dancehall, Reggae, Soca
TRAP & TWERK = Trap, Twerk, Moombah
LATIN = All latin
URBAN = Hip Hop, R&B
RAP = 80s, 90s Rap, Boom Bap
I use genres and label id column in the software to be more specific eg a tracks genre could be Urban, Hip-Hop, Top 40 (a track like Drake’s In My Feeling) in the Label/Comment field i can define the mood a bit. Using the same Drake track as an example [HIPHOP] [PARTY]. I then use color code to define a bit more PINK tracks will be girlie favourites
Blue for tracks i like that i want people to like.
Red for bangers
Yellow for day party, nod your head kinda vibe.
And you know once the girls are dancing the lads are having a good time.
