Xdrive

Xdrive was an online storage company based in the United States. Its key feature was a desktop client which integrated Windows Explorer with the user's Xdrive account. By default, the drive letter mapping was "X:". Early versions of the desktop client were based on WebDrive from South River Technologies. Xdrive was acquired by AOL on August 3, 2005 and provided as a service which allowed users to back up their files over the Internet. It offered a free 5 GB account (free online storage) to anyone with an AOL screenname.
