@Tiphaine > If I understand you correctly, you have your music organized in folders and you want to browse your music in that same structure when exported, correct?
If that's true, what you would want to do is have all of that music originate from the USB drive. In other words, if you currently have it in your computer's Music folder, move it to your USB drive (then relocate all the songs within rekordbox using the relocate function). Then when you export them "to" that drive, it will create pointers, meaning the songs aren't exported because they already exist on that drive. Then you can use the advanced sort / search functions, or because the songs are in your organized folders, you can browse them as you normally would and since they've been analysed, they'll load with the beat grid and other data intact.
