Share stuff from your Dropbox with your Facebook groups. Click Add file from a Facebook group and you're given the option to easily add docs, photos, videos or anything else straight from Dropbox.
Members of the group can then preview the file, download it, or add comments to your post. From now on, the group will be notified whenever you make changes to the file.
Please note that Dropbox and Facebook exchange only the information that's needed for you to add a file to your group. Facebook does not receive other information or access to your Dropbox account.
If you created a new account while linking to Facebook groups, you'll be starting with an empty Dropbox. To learn how to add files to your Dropbox and see some of the other neat things Dropbox can do, complete these easy quests and get some extra free space in the process.
When you share a link, Dropbox creates a unique token used only in that link. It is almost impossible to guess the token, but even if someone was able to, they'd have to know the name of the folder and files the link points to. That said, anyone who can see the link can copy it and post it elsewhere, such as another website.
