iCloud storage in Finder What's the way to use the free iCloud 5GB storage space?
I want to store misc files in there, and access them freely from the Finder/put links to them on my desktop, etc - how do I do it? Couldn't find any intuitive way.

(asking for same functionality like Dropbox/Box.net)

P.S.
Will it be possible to access those files later on from a Windows machine too?
There is a folder, located at ~/Library/Mobile Documents/, that iCloud-enabled apps store their data in. You can trickily use this folder by simply putting any files in there that you want to access from another iCloud-enabled computer. Unfortunately, there's no way to access this folder via the web or on an iOS device, but Macs synced to the same iCloud account will all have your files in that location. I'd recommend creating an alias of some sort as well, to get quick access to it.

In answer to your P.S., there is no way to access this folder on Windows, as it doesn't exist. If you are for some reason only wanting to move iWork files, you can use and access the iCloud web interface on any computer, but I doubt this will help you.
