If you've actually read the files compiled by the FBI, you would know that the FBI files on Hitler's whereabouts after WWII are all reports that they've received from external sources. The FBI was investigating the rumors that Hitler had survived WWII. The files itself are a compilation of all the letters, phone calls and whatever else in between that they have received regarding Hitler after his death.

Just to show you what's inside, I've compiled most of the eyewitness sightings and reports from part 1:
