Hi Kwipper,
Sorry it took so long to get back to you. To browse the files on your SD card in the folder explorer of Cross DJ you need to tap the three dot menu on the top right of the page:

That will bring up a submenu with a storages option. Tap that and you should be able to switch between your internal storage(labeled as default) and sd card(labeled as storage 1).
Best regards,
