Microsoft is getting ready to release its new online storage service called
Windows Live Folders and rumoured for a long time to be part of the Windows Live services suite. Initially it will allow users to store 500MB online, but since this will be a beta this limit will be higher in the actual service, and probably you could even purchase additional storage.
FolderShare promised lots because of its delta sharing capabilities, though Microsoft removed that functionality because it was based on open-source in the original software. Windows Live Folders allows you to create private, public and shared folders. Everything is done through the browser.
Though Microsoft hasn't commented on this, most likely you will have a package of something free and most likely ad-supported. The website at
http://folders.live.com/ link is down at the moment look out for a update for when the site is active and beta sign ups are available.
