I have Dropbox, Dump Truck and Box accounts on my Note 8.0 (Android 4.2.2). When I attempt to upload from the tablet Dump truck and Dropbox will only allow me to upload by file (ticking each file - impractical when hundreds of photos and songs are involved) not by folder. Box will allow upload by folder but will not search the SD card. Dump Truck neither searches the SD card nor allow folder upload. Can anyone help?
