Microsoft renamed its free online storage service Thursday as Windows Live Skydrive, and relaunched it with several interface tweaks as a beta preview open to anyone.
Formerly called Windows Live Folders -- the name under which it briefly made a public appearance in mid-May before vanishing again into invite-only testing -- the service requires users to log in with a Windows Live ID. Most people are familiar with Live ID from accessing Hotmail, now called Windows Live Mail, or using Windows Live Messenger for IM.
Skydrive's storage allowance is 500MB; it lets users create and designate folders as private, public, or public-but-invite-required; and can be accessed using either Internet Explorer (IE) or Firefox. New features or enhancements that debuted in the refresh include image thumbnails and file uploading using drag-and-drop. The latter, however, relies on an ActiveX control, and so can be done only when using IE when accessing Skydrive.
Not a backup service -- it lacks the tools to automate file transfer from local PC to offsite server that, say, Mozy provides -- Skydrive limits individual uploaded files to 50MB or less. Currently, the best is restricted to users in the U.S., the U.K, and India.

Although long rumored to have a similar project in the works, Google has not yet released an "in-the-cloud" storage service -- which has been tagged with the moniker Gdrive -- or even publicly acknowledged one is in testing.
