Consider these statements about folders in an IDE:

Folders are an essential component of organizing a project within an Integrated Development Environment (IDE). They allow developers to structure their files logically, making it easier to manage and navigate through the various components of a project. By categorizing files into different folders based on their purpose or functionality, such as separating source code, resources, and documentation, developers can enhance their productivity and reduce confusion.

While folders do provide some visibility into the layout of the file system, their primary function is not to visualize but to organize. They do not prevent accidental deletion of files as that would depend on other safeguards in place like version control systems or specific IDE features. Additionally, folders can indeed contain files, as well as other folders. Hence, the effective organization of a project is the key reason why folders play such a crucial role in a development environment.
