Where the Built-In iPhone Method Falls Short

  • The iOS Files app merges selected PDFs strictly in the folder's current sort order (such as Alphabetical by filename) rather than the order you tapped them.
  • You cannot combine PDFs located in different folders without moving or copying them into one folder first.
