 It indicates that pyZacros created a uniquely named working folder (``plams_workdir``) and then ran the Zacros calculation in a separate
-subfolder of the working folder (``plamsjob``). All the files created by each Zacros run are saved in the corresponding subfolder for future reference. However, notice that you can access the results directly from the python script. To illustrate this, see line 54 of the script that produces line 6 in the standard output, which prints the number of CO2 molecules produced in the last ten-time steps of the simulation.
