CarotDAV

CarotDAV is a desktop client that lets you manage Dropbox, Skydrive, Google Drive, SugarSync, and other cloud storage services.

The application has a very simple interface that gives you access to each service in a matter of seconds. Just click on the corresponding tab and you'll be able to see all your files.

Before using this program, you have to authorize each storage service via its website. You only have to do this once. Then you'll be able to use CarotDAV to manage your Dropbox folders, for example.

CarotDAV is a useful tool for people who use cloud storage services. The only problem is that you can't modify the files using the application: you'll have to download them to do so.
