As of this week, we've brought product media together with the broader file management system. You can access the file management system from Shopify admin by going to Content>Files
This means that product media is now available within the files section within content in admin. As part of the new update, we’re introducing a reference feature that enables merchants to trace the usage of files in their storefronts. This feature also allows merchants to use references as search parameters, for example a search that only lists files used in product media. Additionally, we’re also launching a new file selector in the online store editor that allows merchants to save views, filter within the selector, and toggle between different types of media as required, all through a new modal design.
