Windows SkyDrive is a service that provides free online file storage and sharing as part of the Microsoft Windows Live suite of Internet services.
To use SkyDrive, register for an account at Windows Live and then log in with your allocated user identification. You can transfer up to 25 Gigabytes of images, audio, videos or documents and access them from any PC with an Internet connection and web browser.
SkyDrive allows drag-and-drop file transfer from PCs; public or secure file sharing; image tagging; group working on shared documents; and secure file backup.
Originally named Windows Live Folders, SkyDrive test launched in August 2007. Microsoft has since rolled out SkyDrive to at least 62 countries, and it is now integrated with other services, including the Bing search engine, Windows Live Office and Windows Live Groups.
