reflect files in folders as playlists

I just want to be able to replicate folder structure in playlist.
Nowadays, I've got several playlists created 1 months ago, my library has changed (I've moved files from directory to another) and I have to recreate all my playlist to make sure no file is missing and older files are well removed from playlist. 

I tried with intelligent playlist but it does not work properly. 

This request is quiet simple, how to do so ?
