Gerhard Rehm General RSTAB

After having updated the RSTAB, my RST files that are being 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 regulate the belonging of the file type?


By default, RSTAB 5 files with the file extension RST are also opened with RSTAB 8. If you use other software that also works with files that have the file extension RST, 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 retained even after an update of RSTAB.
