How do I use the media library?

← All tutorials and guides

Find and Preview Media

  1. Sign in as a teacher.
  2. Open Media from the sidebar, then choose a media category.
  3. Expand folders in the media tree until you find the file.
  4. Select the eye button to preview supported media.
  5. Select Refresh if recent uploads or submissions are not shown yet.

Download or Delete Media

  • Use the download button on a media row or in the preview dialog to save a file.
  • When a file has attached transcripts, LingoLesson may offer separate download choices.
  • Use the delete button to review deletion impact before selecting Delete Media.

Remove Files No Longer Used in a Lesson

Deleting a question, section, or media element in the lesson editor does not permanently delete its underlying file from storage. If no remaining lesson item uses the file, it stays in Teacher Uploads but is no longer included in the lesson list's Assets count after the lesson is saved.

A red, struck-through filename means the file has been checked and is not used in its linked lesson's current saved content. The file is still stored in the cloud. Hover over its filename to see This asset is not used in the lesson. It is still stored in the cloud. Files whose usage has not yet been checked do not show this styling.

This status describes current lesson content. Older student drafts or submissions may still use the file, so check existing student work before deleting it.

To permanently remove an unwanted file, find it under the course and lesson folders, preview or download it to check it, then use its delete button. Review the deletion details and select Delete Media. Permanent deletion cannot be undone; deleting a file that is still used by lesson items will make it unavailable to those items.

When you copy a lesson, only the assets used by its current content are copied. Unused files remain stored with the original; they are excluded from both lessons' Assets counts.

Troubleshooting

  • If a category is empty, no matching media has been created yet.
  • If a lesson item no longer previews after deletion, restore or re-upload the media in the lesson editor.
  • For submission exports, see download or export submissions.
