This script serves as a practical example of how developers can programmatically work with files using MQL5. One of its key objectives is to demonstrate effective project file organization, which is essential for developers working on large-scale systems or aiming to create portable, self-contained projects. The concept can be expanded further and refined with additional ideas to support more advanced development workflows.
