ZeoSpace

ZeoSpace uses the power of the cloud to let you easily back up, access, and share your data.
You can back up files to the cloud by placing them in the special ZeoSpace folder. You can also right click a folder and select the option to back it up to the cloud.
Once the files are in the cloud, you can access them from the browser; no matter where you are, you can log into your account and access your files. Furthermore, your files will be synced across all your devices (if ZeoSpace has been installed on them).
Once the files are in the cloud, you can share them with others: copy/paste the link to a file, share via email, share on Facebook, share on Twitter, share on Google+.

To be able to sync your files across all your devices, ZeoSpace needs to be available for multiple platforms. This is indeed the case. ZeoSpace is available for Windows, Mac OS X, Linux, Android, and iPhone.

To get started with ZeoSpace you must perform two tasks. First up, you must install ZeoSpace on your Windows PC. This is an effortless task that will take little of your time. Next up, you must log into your ZeoSpace account. You can easily sign up for a new account or you can conveniently log in with your Facebook.

The first time you launch ZeoSpace, you will be invited to complete a Knowledge Tour. It will show you how to take a screenshot, how to share a file from the right click context menu, how to back up a folder from the right click context menu, and how to upload photos from the web browser. After completing the ZeoSpace Knowledge Tour you will be awarded with 9GB of free cloud storage space.

You get started with 1GB of free cloud storage space. You can earn 9GB by completing a Knowledge Tour and an additional 1GB by completing an Advanced Tour. You can also earn up to 10GB by referring friends (500MB per friends). That’s all the free cloud storage space you could earn. If it is not enough, you can always get a paid subscription.

ZeoSpace provides easy access to all the functionality you would expect to get from a cloud service: upload files to the cloud, access files from anywhere, sync files across devices, share files with others.
