After an update of RSTAB, my .rst files, which have been used by another program, are always opened with RSTAB. However, the .rst file does not belong to RSTAB, but to another program. How do I control the association of the file type?


By default, the RSTAB 5 files with the .rst file extension are also opened with RSTAB 8. If you use other software that also works with the files that have the -rst file extension, you have to assign the default app for this file extension in the Windows settings. The procedure is shown in the video. This setting is preserved even after an update of RSTAB.
