Ubuntu would like to have a place among these applications, and its creators have already come up with Ubuntu One.
Its big advantage over others services is that it is integrated with the GNU/Linux distribution, something that attracted a lot of its users who also used windows.
The Windows client is very well prepared with a supervision panel that shows us information about our the state of our account, the space on our disk, and the directories to sychronize.
Among the options, we can find the limits for uploading and downloading and activations of automatic synchronization and notifications.
Ubuntu One has become one option to keep in mind for users of Ubuntu who visit Windows often.
