if in one of my medium folder i select one picture i get the message „Medium not used“ but this is wrong, the picture is used in a article.
Ist this a bug or did i missunderstand this message?
Or is there any way to find out files wich are not used?
If you use the relative or absolute URL of the image in a description, blog post, etc. Shopware cannot detect that. Only if a image is linked within a CMS element, a product, category, etc. then Shopware will show you where the image is used.
There is a CLI command to delete all unused images. Be careful, all images included like described above will then be deleted.
