Is it possible to download a folder (or at least download multiple files at once) from Dropbox to SD card?
I do not seem to have the export option when selecting folders
Note the "Share" option doesn't have save to SD either.
ES File Explorer has support for several cloud storage providers. It allows to "copy" folders from your dropbox folder to your SD-Card etc in a similar fashion as you would copy files locally. The "Network" Tab allows you to add an account.
(I don't use the Dropbox app on Android; does it not keep local copies?)
DropSync keeps specified Android folders synced with specified Dropbox folders. No need to export; it's (almost) always there. 'Almost' as in: the changes I make on Android get uploaded right away; changes made to Dropbox files by some other device get downloaded at the next scheduled (or manually initiated) sync. The only time I ever need to think about it is when I have two devices open and I'm working with both of them.
