The missing document in RPD / RE9 is most likely the Library Card file in the STARS Office. It appears only after you open the empty drawer on Albert Wesker’s old desk and wait a few seconds for the file to slide out.

Where to find it

  • Go to the STARS Office in the RPD.
  • Check Wesker’s desk drawer. It looks empty at first.
  • Wait a moment; the Library Card file drops into the drawer.

What it leads to

That file points you to the Medicinal Benefits of Herbs book in the library, which then reveals the Rebecca Chambers photo and helps you solve the STARS briefcase code.

If you meant a different “missing document” in the RPD file list, the other commonly overlooked one is the Guide Pamphlet near the couch after the Mr. X chase.

TL;DR: the most likely missing file is the Library Card in the STARS Office, hidden in Wesker’s desk drawer after a short wait.
