Dropbox, the popular file storage service, has raised another $325 million in funding with the possibility of boosting that amount to $450 million, according to an SEC filing.
The latest funding round had been rumored for a few months, but the amount comes in at the higher end of the range that had been reported. One report last month said Dropbox was raising $250 million at a $10 billion valuation; another report said the amount could be as much as $400 million.

Fortune reports hearing from an unnamed source that the total amount raised in the round to date is slightly higher, at $350 million, still at a $10 billion valuation.
Dropbox previously raised $250 million in a Series B funding round in 2011, which reportedly valued the company at $4 billion. The five-year-old startup is one of several tech companies likely to go public in the near future.
