Are RFEM 5 and RSTAB 8 downward compatible? Can I open files created with these programs in a previous version?


That is possible. If you select "All Files" for the file type in section "Open" of the RSTAB 7, the RSTAB 8 files will be visible as well. They can be opened.

A warning message appears because it is, of course, not possible to consider features that were not contained in the older version.

Another possibility is to rename the file from *.rs8 to *.rs7 and open it directly. The warning message appears even then.

This procedure is the same for RFEM.
