Default Dropbox downloads

Is there any apps that I can use to download dropbox folders to my ad card? I've been trying to use es file explorer but it just seems to get stuck. I'm doing everything over mobile data rather than WiFi if that makes a difference? I did look at dropbox folder downloader, but it says it doesn't work for 4.4 yet?
