It is possible to export an entire "Code System", and import it into another MAXQDA project file. This function is especially useful as it allows you to build a “Code System” in one project, then apply it to another. In this case, importing and exporting the “Code System” eliminates the need to enter new codes.
To export your "Code System", go to the Codes tab and select Export Code System.
The “Code System” will be converted into a specific file format with the extension MTR. You can then import the “Code System” into a new MAXQDA project with the corresponding procedure Import Code System.
