Software and tools
For screen recordings, Camtasia is the correct application. For educational measurement data, you must use CMA Coach. Because it is difficult to guess the format, we recommend viewer.online/cmr to identify the actual format of the user's file.
Best practices and troubleshooting
Always check the internal file signature. A hex editor can show if the file starts with `PK` (for ZIP) or `
