Projects: Principle

In EPLAN, schematics and attached documents such as lists and overviews are created as pages within projects. A project is a database in which, besides the project pages, all master data used in the project (symbols, plot frames, forms, parts data, etc.) is stored.

Thus the project file (*.elk) belongs to a project, as well as the directory where the database and the project-related master data are stored. The project file represents the project; using this file you select (e.g.) a project to open or unzip. It contains the reference to the associated directory containing the project data.

Project files can have different file suffixes, e.g.:

*.elk: Standard project

*.elp: Zipped project

*.elr: Completed project / reference project.
