NEW YORK (TheStreet) -- TheStreet's Ross Kenneth Urken and "Mad Money" Research Director Nicole Urken sat down with Jim Cramer to teach him about Dropbox, the handy file-sharing application.Dropbox, which was founded by two MIT students in 2007, already has 100 million registered users and sees an average of one billion files uploaded per day. "You can do the horrible task of emailing it to yourself or putting in on a USB, but isn't it easier to just have all your files on the cloud?" Ross asked. Cramer asked why he should use Dropbox as opposed to using email or a competitor such as Google ( GOOG) Drive. Ross understood where he was coming from, noting, "We have so many devices already, why add another?" But the Urkens explained some of the time-saving benefits to Cramer. Aside from making it easier on yourself to store and find documents, Dropbox becomes very helpful when working with a group of people or a team. The ability to share specific files or entire folders eliminates the arduous task of sending out individual emails and when you're working with multiple people or teams, this can save plenty of time. It finally hit Cramer when he realized that while Dropbox may only save you a few minutes here and there, a little bit of saved time can go a long way by the end of the day. --Written by Bret Kenwell in New York.
