transfering collection to usb

hi just wanted to if i can from rekord box transfer my whole collection (15k songs) to external hdd with all analyze data, so i can just use the ex.hdd with cdjs?
and making sure all goes in the same way as it is in laptop folder wise...like i got 80`s in one folder and so on it transfers in the same way.
i got latest rekord box i tried drag collection on lef in to usb but that didnt work...it really should have been that easy
