May I know how can get the entire folder uploaded? Or alternatively, how can I select (using multi-select) all files in the current folder?

My intention is to synchronize the photos taken by N9 to dropbox's folder. As far as I can see, there isn't a 'sync' function. Therefore, I want to do it manually by upload the photos once a month by copying the photos in a month to a temp folder for upload purpose.

Any suggestion? Or is it a wishlist item?

Thanks a lot.
