Kiwingu enables you to access your cloud storage as simply as you access your USB pen drives. Kiwingu supports multiple protocols to ensure that you can access your cloud storage without bothering with additional software packages. When using Kiwingu, your cloud drive appears in the Finder the same way your USB pen drives would do when you plug them into your computer. Your cloud drives are accessible from every application on your system, and you don’t have to make a detour through a Web browser or another piece of software just to upload or download a file to or from the cloud.
