ICloud – Cancel iCloud subscription via browser on Windows

You cannot access individual files on iCloud other than the ones made with the iWork suite and that are available on the iWork section of the icloud.com website.

When introducing iCloud, Steve Jobs mentioned that Apple did not think of this service as a big folder in the cloud--a direct contrast with Dropbox. I wrote about this before the launch of iCloud on this Ask Different answer. In short, iCloud is meant to be app-centric.

I would not be surprised if the iWork section of the icloud.com website went away once native iCloud support is added to Keynote, Numbers and Pages. Like it or not, this makes business sense, as it encourages app purchasing.

Hope this helps.

I don't think one is able to access 3rd party app data via www.iCloud.com. You may have a couple options despite that, the first being to get a Mac. Honestly, that's probably not very practical for you. Otherwise, IAWriter, may have a way to log into your account there and access files - a feature not uncommon with apps like that. If neither of those options work, then you will probably have to wait until they put out an app for Windows (which may not be very high on their list if it is on it at all.
