Microsoft OneDrive (formerly SkyDrive) is a desktop client for the SkyDrive cloud service. If you are familiar with Dropbox, you'll find that OneDrive works in a similar manner. It creates a OneDrive folder and whatever file you copy into the folder are automatically synchronized and uploaded with the OneDrive cloud service. You can access your files from other client applications on PC. Mac or mobile devices as well as the web interface. OneDrive also allows you to access all other files on your computer(s), not just the ones in your OneDrive folder. This can come very handy if you need remote access to files that are not synched with the cloud service. The file access features requires an additional security step (email confirmation) and can also be turned off completely.OneDrive requires a Windows Live account and comes with 7GB of free storage.
