I read about Spotdox in the latest MacWorld and it seems useful. Apparently, it hooks into your Dropbox folder and from there gives you remote access to the files on your computer to be copied into Dropbox should you need something and not have it (something that has happened to me more than a few times).

You download the app and copy it into the applications folder (standard stuff). It asks permission to access your Dropbox folder and, remotely, you log into the Spotdox website to access your computer. (I wrote about accessing my computer remotely using Splashtop on the iPad, which works well, but this is a bit more of a targeted app / solution.)

According to MacWorld, it is free for the first 10,000. It’s still free but they’re one download closer to it not being free.
