In order to prevent potential problems in the future, it is recommended to clean your courses from time to time. Large courses can impact Brightspace performance over time and cause issues when completing course copies. Below you will find a few recommendations to decrease the size of your course without impacting your teaching.
Check your course’s content collection for duplicate files and folders.
Check if you have any video or audio files stored in your Brightspace course content.
If you required video assignment submissions in your course, the student submissions can make your course size to exceed your course size limit.
Check your course’s content collection for large files and determine if these could be resized. Ex. PDF Documents, Images, PowerPoints, etc.
Review your course for content that is no longer used.
To save some space in your course, you may add files to your course from Cloud Storage solutions such as OneDrive, Google Drive, or Dropbox.
