I had to upload many files massive and directly to /wp-content/uploads/[year]/[month]/ but those files does not appears in Dashboard>Media>Library
Is there a way to update or refresh it to load those files or it’s simply happening because it should have been writen also in database and I avoided it? In this case, is there a plugin to fix it?
Avoid direct upload WordPress doesn’t scan upload directory for new files, instead use WordPress media uploader to add files WordPress automatically creates folder and store them accordingly.
But you can use this plugin to import those uploaded files into WordPress, it should help you https://wordpress.org/plugins/add-from-server/
