Facebook has acquired most of the assets of Drop.io, a New York-based start-up that lets users privately and sporadically share files through a drag-and-drop interface with additional options like phone calls and even faxing, the company announced Friday on its blog.

Founder Sam Lessin will be joining Facebook full time. Drop.io's service, meanwhile, will be shutting down, making this yet another "acqui-hire" on Facebook's behalf--buy a start-up primarily for its founder, and put that new hire to work developing a new feature at Facebook or improving an old one.

"In the coming weeks, we'll be winding down the drop.io service. As of this week, people will no longer be able to create new free drops, but you'll be able to download content from existing drops until Dec. 15," the post on Drop.io's blog explained. "Paid user accounts will still be available through Dec. 15 and paid users will be able to continue using the service normally. After Dec. 15, paid accounts will be discontinued as well."
