What it is: A password-protected online service that allows you to store and swap files on the Internet

What's cool: Xdrive, owned by AOL, is an easy way to back up important files -- presentations, proposals, even your iTunes collection. And it's compatible with a wide range of operating systems. Simply log on through a Web browser to securely upload or download files. You can also grant colleagues access to certain files without giving away your password.

Drawbacks: It can be time consuming to upload and download your files every time you hit the road or want to work from home. Plus, like many other free AOL services, Xdrive has a Web interface that is wrapped in advertisements.

Price: Free for 5GB of storage; $9.95 per month for 50GB
