Windows Live Mesh

Windows Live Mesh (formerly known as Live Mesh, Windows Live Sync and Windows Live FolderShare) is a free-to-use Internet-based file synchronization application by Microsoft that is designed to allow files and folders between two or more computers be in sync with each other on Windows (Vista and later) and Mac OS X based computers

A beta version Windows Live Mesh Sync "Wave 4" was released on June 24, 2010. This new version, while initially branded Windows Live Sync, was the first version which was built using both FolderShare and Live Mesh technologies. Compared to the "Wave 3" version of Windows Live Sync, the new version featured increased limit of sync folders and files, ability to sync up to 2 GB of files to the cloud on Windows Live SkyDrive synced storage, addition of Live Mesh's remote desktop access via Windows Live Devices, and ability to sync application settings for Internet Explorer and Microsoft Office. This new version of Windows Live Sync was also designed to be completely separate from both the previous versions of Windows Live Sync and Live Mesh, and as such any previous synchronisation relationships were not retained when being upgraded from Windows Live Sync "Wave 3" and Windows Live Mesh. The previous Windows Live Sync "Wave 3" website, and the Live Mesh Desktop, was also replaced by the new Windows Live Devices service in the "Wave 4" release.
The beta Windows Live Mesh was subsequently updated on August 17, 2010, and on August 29, 2010, the service was officially rebranded as Windows Live Mesh, and its cloud-based SkyDrive synced storage was increased to 5 GB, as was the case for the previous Live Mesh service. The new version Windows Live Mesh also allow users to sync hidden files, view a list of missing files that are awaiting to be synchronised, and various performance improvements
