Trouble Opening a .DPLM File? These Steps Will Help

Because .DPLM files can originate from different programs, they aren't universally openable.

  1. Identify the Source: Receiving this from a CAD designer or mapping workflow suggests it contains line coordinates.
  2. Check the Header: Open the file in a text editor or hex viewer to inspect the first bytes:
    • Readable text or XML suggests a plain-text coordinate list.
    • "PK" indicates a zipped archive.
    • Unreadable symbols mean a proprietary binary format.
  3. Use the Original Software: The original program is usually required; try DELPHI 4U's DPLM - Digital Path Lines Memorizer, a CAD viewer, or ask the sender if uncertain.
  4. Use this Webpage: Drag and drop your file into our viewer to detect the format, extract readable text, and preview when possible.
