Box.net is beta testing a new plug-in for Microsoft Office that lets users save Office files to their Box.net storage folders. The plug-in works for both Office 2003 and 2007 on Windows XP and Vista, provides users a new "Save to Box.net" button, and gives visual notification when the file is uploading and then successfully sent. Users can then access that file anytime on their Box.net Web storage folder.
The new plug-in was built using Box.net's developer API, which the Box.net team says can be used to add this functionality to other applications. Box.net is also planning to add support for their network-sharing platform, which supports centralized file access and sharing for multiple users.
This is definitely a worthy download if you're a Box.net user, as it skips the need to fire up your browser and upload your files. However, similar solutions from competing companies offer a more robust option for file junkies. Omnidrive and Xdrive's virtual drives let you open and save remote files right from Word, or any other application for that matter, although I have a feeling Box.net isn't that far behind with their own virtual drive solution.
