Data belonging to Megaupload users could still be retrieved.
Non-profit group, the Electronic Frontier Foundation (EFF), supported by Carpathia Hosting, today announced its plans to assess Megaupload users who are at risk of losing their data.
The two parties have agreed to preserve the data of Megaupload and will work with US prosecutors.
The site's data has been held by Carpathia and Cogent Communications Group since the site was shut down.
The US is seeking to extradite Megaupload founder Kim Dotcom and
three other defendants for allegedly robbing copyright holders of
more than $612m in revenue.
"Carpathia and Cogent agreed to preserve consumer data for additional time of at least two weeks so Megaupload can work with US on proposal," Ira Rothken, the lawyer for Megaupload's found Kim Dotcom tweeted today.
Users have been unable to access data since the file storing service was shut down earlier this month.
It was earlier thought that data would begin to be deleted from today.
The news could come as relief for one Megaupload user who emailed ONE News.
"All my data and my lifetime premium money was stolen by the FBI on 19 Jan 2012."
"I am not from the US and not under US law. I use the service to store my files and backup files. I don't share copyrighted materials."
The user said they simply want their backup files back.
"My files which include personal ones and years of hard work worth more than a thousand of dollars, and my account is worth $199, which I am using for non-sharing purpose.
"FBI, please return all my money and property which you have seized within 1 day, or rather stolen, without any warrant presented or warning."

Millions face data loss
Rothken told the Associated Press that of the service's 150 million registered users; at least 50 million faced losing their data.
Although the US copied some data, it did not remove any servers from the premises of either storage company.
A letter from the US Attorney's Office explains that the data "remains at the premises controlled by, and currently under the control of Carpathia and Cogent".
The US Attorney's Office letter stated, "Should the defendants wish to obtain independent access... that issue must be resolved directly with Cogent or Carpathia."
Megaupload has about 50 million registered users, making it one of the most popular file-storing services in the world.
