What is a CON file?

CON files mostly belong to Text Editor / App-Specific. CON files are not uniform in design. They serve as containers for data may be used to store configuration settings or technical information.
Many applications use this extension in ways specific to their functions. For example,

Game and Simulation Configurations: Certain files hold setup preferences for games (such as the configuration settings for a title like Battlefield 2) or simulation software (e.g. a train simulator file that even uses UTF-16 (LE) encoding).

Technical and Order Data: Other CON files record details like clothing orders or technical data used in production. These may include garment order instructions or even dental scan data.

Specialized System Settings: Some are dedicated to control and configuration of hardware such as robots from Daihen Welding Controller (Daihen) or CNC machine settings for programs like Delcam PowerMILL (Autodesk PowerMILL Overview). Additionally, word processing applications like WordPerfect store configuration details in CON files (Corel), and simulation games (for example, Transport Fever 2) use them for construction data.

These files are typically text based and can be opened with a text editor if the content is in plain text. However, special encoding (such as UTF-16) or proprietary formatting in some cases may require the use of the specific software that created them.
FilExt.com tip: Use a reliable editor and always back up the file before making changes.

How to open CON files
