原文外掛簡介
s404 Orphaned Attachment Scanner helps you find and remove media files that are sitting in your WordPress Media Library but are not used anywhere in your installation — not in posts, pages, widgets, theme customizer, ACF fields, WooCommerce products, page-builder data, or any active plugin’s settings.
Features
Batched AJAX scan — never times out on large libraries
9 detection layers — post content, post meta, featured images, widgets, theme customizer, ACF, WooCommerce, page builders (Elementor, Beaver Builder, Divi, Bricks…), ALL active plugin wp_options
Filesystem scan — checks theme files and optionally the entire WP installation for hard-coded references
Format filtering — scan only images, video, audio, documents, or specific formats (JPEG, PNG, WebP, SVG…)
Age threshold — only flag files older than N days, protecting freshly uploaded assets
Trash & Permanent Delete — move items to Trash for safety (requires define('MEDIA_TRASH', true); in your wp-config.php to enable the media bin)
Deletion log — every action is recorded with timestamp and username in your local history
Bulk actions — select, trash, delete, exclude, or export to CSV
Exclusion list — permanently hide specific IDs, MIME types, or path patterns from scan results
Scheduled scans — WP-Cron with daily/weekly/monthly frequency and optional email report
Developer hooks — s404as_is_attachment_used filter, s404as_before_delete / s404as_after_delete actions
