A Megaupload client is trying to get his digital property back, through the courts in the United States.
Kyle Goodwin, from Ohio, used the site legitimately to store videos for his work filming high-school sports teams.
After the site was shut in January and founder Kim Dotcom was arrested, Mr Goodwin and thousands of other people lost access to their stored material.
A judge in Virginia handling the case has now decided there needs to be a separate hearing to decide how to handle the digital information stored legally on Megaupload.
The Electronic Frontier Foundation in San Francisco is representing Mr Goodwin's case in court. It says the case will decide whether people who stored data legally on the site, can have it returned.
