Mahmud Nacua, Libya's ambassador to Britain, said it would be at least another year before the files are made public as a newly restructured government establishes security and stability.
One of Scotland's top prosecutors wrote to Libyan Prime Minister Ali Zeidan recently, asking for "swift progress and cooperation" regarding the release of the files, the BBC reported Friday.
Earlier this year, Scotland's Lord Advocate Frank Mulholland met with Libyan interim Prime Minister, Abdurrahim Abdulhafiz el-Keib, to discuss the bombing.
"The prime minister asked for clarification on a number of issues relating to the conduct of the proposed investigation in Libya and the lord advocate has undertaken to provide this," the Crown Office spokesman said at the time.
"The prime minister made it clear that he recognized the seriousness of this crime and following the clarification he would take this forward as a priority."
