Megaupload, one of the most popular file-sharing services in the world could lose all its data, legal or illegal on Thursday, 2nd of February 2012 according to the Associated Press. US Prosecutors warns Megaupload users that they will eventually face data deletion.

According to Ira Rothken, Megaupload’s lawyer, at least 50 million users who had stored data could be deleted but it is doing its best to keep the data from being removed. “We’re cautiously optimistic at this point that because the United States, as well as Megaupload, should have a common desire to protect consumers, that this type of agreement will get done,” he said.

Megaupload was shut down last January 19 and the data which might be deleted was being held by Carpathia Hosting and Cogent Communications Group storage companies. The letter from the US prosecutors said that as of the moment the selected data were copied and the servers were not yet removed from the premises controlled by the said storage companies.
