<h4>Why This Plugin Is Different</h4>
<p><strong>Most media cleaner plugins help you delete unused images. This plugin fixes a fundamental WordPress problem first.</strong></p>
<p>WordPress has a built-in “Unattached” filter in the Media Library. The idea is simple: it shows you media files that aren’t connected to any post, so you can decide whether to keep or delete them.</p>
<p><strong>The problem?</strong> WordPress only marks media as “attached” if it was uploaded directly through the post editor. Any image added through ACF fields, Gutenberg blocks, page builders, widgets, theme options, or shortcodes shows as “Unattached” — even though it’s actively being used on your site.</p>
<p><strong>This makes WordPress’s native “Unattached” filter completely unreliable.</strong></p>
<h4>How Unattached Media Manager Fixes This</h4>
<p>This plugin scans your entire site, finds every place where media files are actually being used, and properly attaches them to their parent posts. Once attached:</p>
<ul>
<li><strong>WordPress’s “Unattached” filter actually works</strong> — It now shows only truly unused media</li>
<li><strong>You can use WordPress’s native tools</strong> — No need to depend on third-party plugins to manage media</li>
<li><strong>Import/export plugins work correctly</strong> — Tools like WP All Import, WP Migrate, Duplicator, and others can now properly identify and migrate media with their associated posts</li>
<li><strong>You can safely uninstall this plugin</strong> — The attachments remain as part of WordPress’s native structure</li>
</ul>
<h4>The Workflow</h4>
<ol>
<li><strong>Scan</strong> — The plugin finds all media usage across your site (content, ACF, blocks, widgets, options, etc.)</li>
<li><strong>Attach</strong> — One-click to properly attach all “used but unattached” media to their parent posts</li>
<li><strong>Review</strong> — Now WordPress’s “Unattached” filter shows only genuinely unused files</li>
<li><strong>Clean Up</strong> — Use WordPress’s native tools OR this plugin’s safe deletion features</li>
<li><strong>Done</strong> — Uninstall if you want; the fixes stay with WordPress</li>
</ol>
<h4>Yes, It Also Deletes Unused Media</h4>
<p>Like other media cleaners, this plugin also helps you safely delete unused media with:</p>
<ul>
<li><strong>Trash support</strong> — Move to trash first, restore if needed</li>
<li><strong>Permanent delete</strong> — Remove forever when you’re sure</li>
<li><strong>Change history</strong> — Track all attachment changes with one-click revert</li>
</ul>
<p>But the real value is <strong>fixing WordPress’s attachment system</strong> so you don’t need to depend on any plugin long-term.</p>
<h4>Two Processing Modes</h4>
<ul>
<li><strong>Browser-Driven (Recommended)</strong> — Fast and reliable with real-time progress. Keep the browser tab open until complete.</li>
<li><strong>Background (WP-Cron)</strong> — Processing continues even after closing your browser. Ideal for server cron setups.</li>
</ul>
<h4>Key Features</h4>
<ul>
<li><strong>Comprehensive Scanning</strong> — Detects media usage in post content, featured images, Gutenberg blocks, ACF fields, Elementor, Meta Box, WooCommerce, SEO plugins, widgets, theme options, and more</li>
<li><strong>Fix Unattached Media</strong> — One-click to properly attach all “used but unattached” media</li>
<li><strong>Media Library Integration</strong> — See usage count directly in your Media Library list view</li>
<li><strong>Safe Deletion</strong> — WordPress trash support with restore capability</li>
<li><strong>Change History</strong> — Full audit trail with one-click revert for any attachment</li>
<li><strong>Pause & Resume</strong> — Stop any operation and continue later</li>
<li><strong>Resource Aware</strong> — Three modes (Low/Auto/High) for shared hosting to dedicated servers</li>
<li><strong>Export Reports</strong> — Download CSV reports of all media usage</li>
<li><strong>Developer Friendly</strong> — Hooks, filters, REST API, and WP-CLI commands</li>
</ul>
<h4>The Problem It Solves</h4>
<p>WordPress marks media as “Unattached” if it wasn’t uploaded directly to a post. But many media files ARE being used — they’re just embedded via:</p>
<ul>
<li>The block editor (Gutenberg)</li>
<li>Page builders like Elementor or Beaver Builder</li>
<li>ACF image/gallery fields</li>
<li>WooCommerce product galleries</li>
<li>Theme customizer settings</li>
<li>Widget areas</li>
<li>Shortcodes</li>
<li>Custom meta boxes</li>
</ul>
<p><strong>Unattached Media Manager finds ALL these references and properly attaches the media</strong>, so WordPress correctly reflects which files are actually in use.</p>
<h4>Server-Friendly Design</h4>
<p><strong>This plugin is designed to work on ALL servers, including shared hosting with limited resources:</strong></p>
<ul>
<li><strong>Never blocks your site</strong> – All heavy operations are processed in batches</li>
<li><strong>Adaptive resource usage</strong> – Automatically detects server limits and adjusts accordingly</li>
<li><strong>Three resource modes:</strong>
<ul>
<li><strong>Low Resources</strong> – 5 items/batch, 2-minute intervals (for shared hosting)</li>
<li><strong>Auto (Recommended)</strong> – 15 items/batch, 1-minute intervals (adjusts automatically)</li>
<li><strong>High Performance</strong> – 50 items/batch, 30-second intervals (for dedicated servers)</li>
</ul>
</li>
<li><strong>Two processing strategies</strong> – Choose browser-driven (fast) or background WP-Cron mode</li>
</ul>
<h4>Supported Content Types</h4>
<p><strong>ALL features below are FREE – no Pro version required!</strong></p>

<h4>For Developers</h4>

<ul>
<li><strong>Hooks & Filters</strong> – Extend scanning with custom parsers</li>
<li><strong>REST API</strong> – Query media usage programmatically</li>
<li><strong>WP-CLI Commands</strong> – Run scans from the command line (<code>wp aioms scan</code>)</li>
<li><strong>Custom Post Types</strong> – Automatically scans all public post types</li>
</ul>
<h3>How to Use</h3>
<h4>Step 1: Run Your First Scan</h4>
<ol>
<li>Navigate to <strong>Media <span aria-hidden="true" class="wp-exclude-emoji">→</span> Media Solution</strong></li>
<li>Click <strong>Start Full Scan</strong></li>
<li>Choose your processing mode (Browser-Driven recommended for most users)</li>
<li>Watch the real-time progress as your media library is scanned</li>
</ol>
<h4>Step 2: Review the Dashboard</h4>
<p>After scanning, you’ll see:</p>
<ul>
<li><strong>Total Media Files</strong> – All attachments in your library</li>
<li><strong>In Use</strong> – Media files with detected references</li>
<li><strong>Potentially Unused</strong> – Media files with no detected references</li>
<li><strong>Used but Unattached</strong> – Media that’s used but marked as “Unattached” in WordPress</li>
<li><strong>Total References</strong> – Total number of places media is referenced</li>
</ul>
<h4>Step 3: Fix Unattached Media</h4>
<p>If you have “Used but Unattached” media:</p>
<ol>
<li>Click the <strong>Attach All Media Files</strong> button</li>
<li>The operation runs in the background</li>
<li>Each attachment is tracked in Change History for easy reverting</li>
</ol>
<h4>Step 4: Clean Up Unused Media</h4>
<p>Go to the <strong>Unused Media</strong> tab to:</p>
<ol>
<li><strong>Review</strong> – Check each file before taking action</li>
<li><strong>Move to Trash</strong> – Safely move to WordPress trash (can be restored)</li>
<li><strong>Restore</strong> – Bring items back from trash if needed</li>
<li><strong>Delete Permanently</strong> – Remove forever (cannot be undone)</li>
<li><strong>Empty Trash</strong> – Delete all trashed media at once</li>
</ol>
<p><strong>Important:</strong> All bulk operations run in the background. You’ll see a status bar showing progress.</p>
<h4>Step 5: Review Change History</h4>
<p>The <strong>Change History</strong> tab shows:</p>
<ul>
<li>All attachments made by this plugin</li>
<li>When each change occurred</li>
<li>What post each media was attached to</li>
<li>Option to <strong>Revert</strong> any change (detaches the media)</li>
</ul>
<h3>Important Precautions</h3>
<h4>Before Deleting Any Media</h4>
<ol>
<li><strong>Always run a full scan first</strong> – Make sure the index is up to date</li>
<li><strong>Review files manually</strong> – The scanner detects database references, but images might be:
<ul>
<li>Hardcoded in theme PHP files</li>
<li>Used by external websites linking to your images</li>
<li>Referenced in custom code or third-party plugins not yet supported</li>
<li>Used in email templates stored outside WordPress</li>
</ul>
</li>
<li><strong>Use Trash first</strong> – Move to trash instead of deleting permanently</li>
<li><strong>Wait before emptying trash</strong> – Keep trashed items for a few days to catch any issues</li>
</ol>
<h4>About “Potentially Unused” Media</h4>
<p>Files marked as “Potentially Unused” means:</p>
<ul>
<li>No references were found in the scanned content</li>
<li><strong>This doesn’t guarantee the file is unused</strong></li>
<li>The file might be used in ways not detected:
<ul>
<li>Theme template files (hardcoded)</li>
<li>External sites linking to your images</li>
<li>Custom plugins with non-standard storage</li>
<li>CSS background images defined in stylesheets</li>
<li>JavaScript-loaded images</li>
</ul>
</li>
</ul>
<h4>Recommended Workflow</h4>
<ol>
<li><strong>Scan</strong> – Run a full scan with all content types enabled</li>
<li><strong>Review</strong> – Look at the Unused Media tab</li>
<li><strong>Research</strong> – For each file, consider where it might be used</li>
<li><strong>Trash</strong> – Move questionable items to trash (not permanent delete)</li>
<li><strong>Monitor</strong> – Check your site for a few days for missing images</li>
<li><strong>Delete</strong> – Only permanently delete after confirming no issues</li>
</ol>
<h4>Server Resources</h4>
<ul>
<li><strong>Shared Hosting</strong> – Use “Low Resources” mode in settings</li>
<li><strong>If operations timeout</strong> – Switch to Low Resources mode</li>
<li><strong>Large media libraries</strong> – The scan may take longer but will complete</li>
<li><strong>WP Cron must work</strong> – Ensure WordPress cron is running (check with your host)</li>
</ul>
