Hi guys,
I had to cancel a PARFOR simulation because of low disk space.
I think MATLAB didn't react too well and I think I lost some disk space.
Where should I check for temporary stored logging files that might not have been deleted?

The issue is resulting mainly because you are logging a very large amount of data which results in very large temporary files as you have mentioned. Temporary files are usually ‘.dmr’ files created by SDI (Simulation Data Inspector) at 'C:\Users\username\AppData\Local\Temp\'.
1. Please run the following command in MATLAB:
>> tempdir
>> Simulink.sdi.getSource %Return location for storing simulation data
2. Using Windows Explorer, navigate to the tempdir path listed in the result from Step 1. You can find the “.dmr” files here. Delete all files with the type "DMR" to remove prior session data if needed.
