With its set of new features, Dropbox is moving away from file sharing and into the realm of “content.” The goal is to be much more than just a personal storage system.

The cloud storage provider with over 100 million users released new features today at a press event at its San Francisco office. These include quick previews for PDFs and other documents, and more intuitive sharing capabilities for Facebook, Twitter and email. These updates are for the Web-based version of Dropbox, and will be released by the end of the month.

Dropbox is stressing in its messaging that it wants to be associated with “content” rather than files. But as AllThingsD points out, the company still has a long way to go. It’s difficult to scroll through photos that are grouped into albums, and there are no editing capabilities to augment the document preview tool.

Dropbox currently competes with Box, a cloud storage provider that yesterday filed the paperwork for a $150 million Series E round. It also faces off with SkyDrive and iCloud, which is further incentive for the company to add value to its users beyond simple share and sync.
