How to open .DOR files on Windows

To open .DOR files on Windows, install and open Graphisoft Archicad, then use its library/object workflow to import/load the .DOR file (commonly treated as a Door library part).

Step-by-step instructions

  1. Install and open Graphisoft Archicad, then use its library/object workflow to import/load the .DOR file (commonly treated as a Door library part).
  2. If double-clicking doesn’t work, right-click the file → Open with → choose Archicad (or set Archicad as the default app for .DOR if appropriate).
  3. If you don’t have Archicad, ask the sender to provide an Archicad-compatible alternative export intended for your software (or a different deliverable), because .DOR is not a general viewer-friendly format.

Alternative methods

  • Open .DOR in a browser-based viewer if desktop apps fail.
  • Try opening .DOR on Windows with a secondary app to rule out app-specific issues.
  • Convert .DOR only with trusted tools when direct opening is not possible.

Common issues

Windows/macOS says it can’t open the .DOR file

This usually happens because the system doesn’t have an application associated with .DOR, or Archicad is not installed.

  1. Install Graphisoft Archicad and open the file through Archicad’s library/object workflow.
  2. If Archicad is installed, use “Open with” and explicitly pick Archicad, then set it as the default for .DOR if you frequently receive these files.

The .DOR file opens, but the door/object is missing or not usable in the project

Library parts can depend on how libraries are loaded and how the project/library paths are set up inside Archicad.

  1. In Archicad, confirm the relevant library is loaded and that the .DOR file is included via the library management workflow.
  2. Ask the sender for the complete library package needed for the object (not just a single .DOR file) if you suspect dependencies.

You’re trying to open .DOR on mobile (iOS/Android) or Linux

.DOR is not a common consumer document format and typically requires Archicad on desktop platforms.

  1. Move the file to a Windows or macOS computer with Graphisoft Archicad installed.
  2. If you only need a visual reference, request a separate deliverable from the sender that is intended for viewing (rather than a library-part source file).

The file seems to be the wrong type (unexpected content/behavior)

File extensions can be misapplied. A .DOR file should come from an Archicad/GDL library context; otherwise it may be mislabeled.

  1. Verify the source and context: was it exported from or used by Archicad as a door library part?
  2. If uncertain, do not force open it with unrelated apps; ask the sender what application created it and request the correct file or a different format.

Security note

.DOR files are commonly tied to Archicad’s GDL/library part ecosystem; treat them as inputs to a complex parser (Archicad). Only open .DOR files from sources you trust.
