Enrol Sync: Course deletion file generator screen
This screen provides a utility to quickly generate a suitable course deletion batch file from the actual course list of your Moodle. The produced file is stored in the Sync File Manager.

The screen is divided in two areas:
On top you will have an overview of existing courses, with a short summary of how many people in each. On the lower part, you will choose the course to be deleted so a course deletion file is generated.
Why not deleting courses right now ?
On huge Moodles, or on Moodle that are intensively and frequently used, processing a big deletion batch can have consequences for connected users. It may be safer to check and re-check the deletion list, and to wait a quiter moment to schedule the deletion.
