From the developer:
Boxifier is a program that enables you to sync and backup any folder to Dropbox. It sends your data from your external drive directly to your Dropbox account, without copying it to the Dropbox folder on your computer. If you disconnect your external drive, Boxifier will make sure the files you synced from that drive won't get deleted from your Dropbox account.
