RFEM/RSTAB have an integrated backup function. You can find it in the working directory of the program. The current models are created here as subfolders of the program version. They contain all the files created during the input and calculation, including the backup file Position.bak.
The working directory is created after the installation. You can find the file location using the menu "Options → Program Options" in the "Data Files" tab when setting the Working Directory category.
Copy the Position.bak file to another folder and rename it "Modell.rf5" or "Modell.rs8". Thus, you can open the file with RFEM or RSTAB.
The Position.bak file is automatically deleted when you quit the program properly. However, if the program crashes, the file still exists. You can restore it as described. When you open RFEM/RSTAB after a program crash, a message appears asking whether the backup file (Position.bak) should be opened again. Click [Yes] to confirm and the backup file will be loaded.
Please note:The automatic backup file will be overwritten as soon as you start working with another model or if you leave the old model open for too long (for example, a day).
You can define the interval of automatic file saving using the menu "Options → Program Options" in the "Program" tab.
