FriendFeed rolled out a new file-sharing feature on its site this afternoon in hopes of encouraging more organizations to use FriendFeed as a collaboration tool.

On its blog, FriendFeed explained:

This has been an especially popular request from organizations and companies that collaborate using FriendFeed groups. We’ve certainly been using this feature internally and have found it extremely useful. We hope it’ll help make you and your collaborators even more productive, and a little more attached to FriendFeed.

With today’s move, the collaboration space is getting crowded. Adobe recently took Acrobat.com out of beta and introduced its subscription service for businesses.

“Sharing files is really crucial within a company or organization,” FriendFeed CEO and co-founder Bret Taylor told us. “By adding this feature, we’re hoping more companies will look at FriendFeed as a collaboration tool.”

FriendFeed users can upload files either on the site or by email. People can upload files by clicking the “Files” link under the post box on the FriendFeed page. To send a file by email, you send the file as an attachment to share@friendfeed.com. FriendFeed users can upload anything from a Microsoft Office document to a Photoshop mock-up, but executable files and video files are restricted. While uploading audio files is permitted, FriendFeed lets users upload only three MP3 files a day as an attempt to crack down on copyrighted music file-sharing.

Taylor wouldn’t specify the daily MB limit users are restricted to when uploading files because FriendFeed plans to change the limit as more people use the new feature.
