Cloud storage start-up Dropbox just got some more friends--millions of them, in fact.

On Wednesday, the company announced its integration with Facebook, which will allow people in Facebook groups to share files with one another via Dropbox. 

"Now you can share notes with your study group, add the latest game schedule to your basketball team's group, or post a birthday video to your family's group at lightning speed from wherever you are," Dropbox engineer Chris Varenhorst wrote in a blog post. Businesses can also share files with one another and collaborate on specific projects remotely through Facebook groups with the addition of Dropbox.

CNET reports that while the integration certainly has positive ramifications for Dropbox by potentially by adding to its customer base, Facebook’s motives for the integration seem less clear. The social media site added its own group-sharing feature in May, but now it will steer users away from it and towards Dropbox, a third-party application. Facebook referred to Dropbox as a "trusted partner."

"Our teams worked hard to create a simple and accessible solution that allows users to instantly upload and discuss files of all types and sizes," a Facebook spokesperson told CNET.

Founded in 2007 and an alum of the Y Combinator incubator program, Dropbox has raised a total of $257 million in funding, according to Crunchbase. The company acquired stealth start-up Cove for an undisclosed amount earlier this year and recently partnered with Vimeo to help streamline video uploads to the site.
