Here’s a nifty add-on to Box.net, the free on-line file management service. A small 270 Kb download integrates with Microsoft Office 2003 or 2007 to provide a one-click option for storing your Office artifact in your Box.net vault. Yep, anything you can create in Word, Excel, Access or Powerpoint can quickly be shuffled through the Internets and stored in your Box for later or shared access. Aside from the 5 GB of free storage, Box.net does provide the ability to add users to your account for viewing or editing stored files. Definitely a nice tool for file sharing and storage when you’re on the go.
