How do I download an entire directory from Dropbox?
If you are accessing Dropbox using a browser, you can select the folder you wish to download by highlighting it, then click the "Download" option on the menu above (see screenshot). Dropbox will then zip the whole folder and let you download it that way.

Click the ... button to the left of your folder, then click Download in the newly opened window. You'll then be prompted to save the entire folder as a .zip file.
