MEDIA_THUMBNAILS_NOT_REMOVED

Cause

Some left-behind thumbnails could not be removed, or could not be checked just before their removal.

With --apply, each listed thumbnail is checked against the media table again just before it is removed. Some were left: the storage refused to remove them, or the check before removal could not be made. The Why line names each.

Fix

• Read the reason the Why line gives for each file: a storage permission is the usual cause.
• Run nextly media orphans --apply again to list and remove what is left.

Example

✗ 1 left-behind thumbnail(s) were not removed.
  Why:  Could not remove media/2026/10/0b7f0b0e-thumb_x.png: AccessDenied: Access Denied
  Next: Run `nextly media orphans --apply` again to list and remove what is left.
