media_duplicate_check

Features

Media Duplicate Check prevents accidental duplicate media uploads by checking filenames and showing existing media items. This module automatically detects when users try to upload files with names that already exist in the media library and provides visual feedback about existing media items.

• Duplicate Detection: Automatically checks for existing media files with the same filename during upload
• Visual Preview: Shows thumbnails and details of existing media items with the same filename
• Configurable: Admin settings to control which media types are checked and how the module behaves
• AJAX-powered: Real-time checking without page reloads
• Multiple Media Type Support: Works with images, documents, SVG files, videos, and audio files
• Translation Ready: Supports multilingual sites with translatable strings
