The data of an RFEM/RSTAB structure are saved as packed by default. If this packing process is interrupted or disturbed by other software, a faulty archive may occur.

To avoid this problem in the future, please save very large files locally on your PC and then move them to a network path, if necessary.
Please pay attention to the correct settings in your antivirus software, as it may also cause problems when reading and writing data.
