FileSonic has disabled its file sharing services following a crackdown on MegaUpload amid heated debate over U.S.-led attempts to clamp down on online piracy.

The Megaupload group has been accused of engaging in a scheme that took more than $500 million away from copyright holders and generated over $175 million in proceeds from subscriptions and advertising. Megaupload's lawyers have said the company simply offered online storage. The inverstigations are led by the U.S. Federal Bureau.

Like Megaupload, FileSonic is providing providing online data storage. The company has disabled the sharing functionality and currently only allows users to access their own files.

"All sharing functionality of FileSonic is now disabled. Our service can only be used to upload and retrieve files that you have uploaded personally," reads a statement on the FileSonic website.

The debate over online piracy is increased in Washington where Congress is trying to craft tougher legislation.
