DREAM Suite project data is stored in the main project file and a directory containing other files and subdirectories. Project directory name is derived from the project name by adding Drm_ prefix (see Figure 5.1.1. "Project file and directory"). This means that, if you are copying of deleting a project, you must copy/delete both - the file and the directory. The main project file (*.drm) and simulation files (so called "case files" - *.drs) are text files with a very simple format and can be easily edited using Notepad or another text editor.
Figure 5.1.1. Project File and Directory.
Project Directory
- Drm_Examle01 - project directory of project "Example01"
- Model - directory for model-specific files
- Bin - external executable files (see Example07)
- Data - static model data, such as measurement data, etc. (see Example07)
- Info - contains file ProjectInfo.htm with detailed description of the project
- Plugin - directory for plugin files
- Bin - contains the plugin 32-bit dynamic library
- Bin_x64 - contains the plugin 64-bit dynamic library
- Src_Cpp - contains plugin C/C++ source code (Visual Studio project and plugin source code)
- Src_Matlab - contains MATLAB *.m files if the plugin type is MATLAB COM or MATLAB Engine
- Src_Python - contains Python files if the plugin type is Python (not available in the current version)
- Simulations - directory for simulations. Each simulation has its data in a file and a special directory
- Case1.drs - so called "Case File" with input data of simulation "Case1"
- Case1 - so called "Case Directory" for output files of simulation "Case1"
- CaseX.drs - file with input data of simulation "CaseX"
- CaseX - directory for output files of simulation "CaseX". Files can be in text format (*.txt) or binary format (*.bin) according to the selected option "Save results in binary format"

- Temp - temporary directory. Contains a working copy of the Simulations directory while the project is open and its content is deleted when closing the project. Case directories may contain additional subdirectores named 1,2,3,...,N that are created during parallel calculation and their names 1,...,N correspond to the number of calculation threads (cores).
