Opening PLN files

Did your computer fail to open a PLN file? We explain what PLN files are and recommend software that we know can open or convert your PLN files.

What is a PLN file?

The .pln file extension is most commonly associated with the ArchiCAD design software. ArchiCAD is used to create architectural design projects. Files with the .pln extension are project files that contain a 3D model that has been created by the software.

The .pln file extension is also used for CTP scene definition files, Microsoft Flight Simulator flight plan files, Adobe InDesign plugin files and Psion Organizer spreadsheet files.

Try a universal file viewer

In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
