Files that contain the .ptn file extension are most commonly associated with the PaperPort document management software application that is distributed by Nuance Communications.
The PaperPort software is used to scan and organize documents and share the documents with other users via email or the Web. The PTN file contains the information that is needed by the software to display the thumbnail images associated with the application. These files are normally hidden within a user's system.
The .ptn file extension is also used by the CADKEY software program. This application uses the .ptn file suffix for the pattern files that are utilized by the program.
