Move file to folder in dropbox
I'm working from the iPhone app so it may be different on the iPad, but try this.


Browse to the file you want to move.
Tap the ellipsis ( ... ) at the top of the screen next to the folder name, and choose 'Edit'.
Tap the checkbox next to the file you want to move.
Tap 'Move' at the bottom of the screen.
Navigate to the folder you want to move the file to.  You can use the arrow at the top left to go to the parent folder.
When you are in the desired destination folder, tap 'Choose' at the bottom right corner of the screen.
