In addition to this, Houston also shared that 100 million users tap into the service with 500 million devices - PCs, smartphones and tablets.
Dropbox was founded in 2007 by Drew Houston and Arash Ferdowsi. At the time of launch, Dropbox could only sync files between different computers, but with time added support for smartphones and tablets. The company's current valuation is being pegged at a staggering $4 billion.
The company had 100 million users as of November 2012. It is present on almost all popular mobile and desktop platforms including Windows, Mac, Linux, iOS, BlackBerry and Android. Unofficial ports also exist for Symbian and MeeGo platforms. The company recently rolled out an app for Windows 8 devices but Windows Phone 8 is yet to get an official Dropbox app.
Earlier in February, the company had rolled out its first comprehensive upgrade to its cloud-storage product aimed at corporate users. With the help of Dropbox's new software IT administrators will be able to closely track which users have viewed a file and when it was viewed. Furthermore, the IT administrators can now instantaneously grant or withhold file permissions. The software also allows administrators to rope off certain files so they may be edited but not downloaded or shared in any way.
Dropbox has a strategic tie-up with leading smartphones makers such as Samsung and HTC. Under this partnership, users logging into Dropbox via select Samsung or HTC smartphones will get extra storage space for a limited period of time. For example, Samsung is offering 50GB of cloud space from Dropbox for two years with the purchase of Samsung Galaxy S III and Samsung Galaxy Note II.
