How to recover simulink dmr files

I have a large simulink .dmr file with simulation results. is there a possibility to open this file and view the results?

The simulation crashed because the .dmr ocupied all the left space on C://

Hi Florian.

If you think that your .dmr file is large for your model, you can also reduce it's size by reducing the amount of logged data. You can find more information on the following link:

These .dmr files are not intended to be directly opened or accessed by the user. Instead, they act as a storage backend for Simulink's logging during the simulation. Once the simulation completes, the data is typically available in the MATLAB workspace or wherever you've configured the logging to save to, and the .dmr file is just a temporary store.

I would suggest that you either reduce the size of the .dmr file by changing the configuration or clear some space on your "C://" drive so that the Simulation doesn't crash when you run it next time.

These .dmr files are usually stored in a temporary folder and will automatically get deleted once MATLAB closes.

@Florian Schindler - and I think the answer to your direct question is, no, there is nothing useful you can get from that file except the important lesson to reduce the information logged and probably to increase the space available for that purpose, and to re-run the analysis. The file is not designed to be read. And anything in the file is corrupted anyway, since the file would not have been properly closed in the crash.
