If your model requires additional files, such as Matlab scripts, or dynamic link libraries, you can define them by double clicking the unit operation and selecting the Additional Files tab. Here, you can add existing and new files, edit files, rename files and remove files.
The files are saved with the unit operation, as well as in model files. If you add a file, changing the original file will not affect the copy stored in the unit operation. If required, you can remove and re-add the file.
You can export the additional unit operation files by clicking on the Save As button.
