media_dupe_detect

Features

The Media Duplicate Detect module enhances the Media Library experience by automatically identifying duplicate file uploads. When a user attempts to upload a file that already exists, the module checks the file hash and suggests using the existing media item instead.

Key features include:

• Detects duplicate media items based on file hash
• Prompts users to reuse existing media instead of uploading duplicates
• Role-based permission to bypass duplicate detection (for trusted users)
• Field-level configuration for enabling duplicate checks

Use cases:

• Keep your Media Library clean and organized
• Avoid bloating your site with repeated uploads of the same image or document
• Improve media management for large content teams or editorial workflows

Post-Installation

After enabling the module and its dependencies:

1. Go to the form display configuration of the content type or entity type using a media field.
2. Click the gear icon on the Media Library widget settings.
3. Enable the “Detect duplicates” checkbox to activate duplicate detection for that field.
4. Navigate to People > Permissions to allow specific roles to bypass duplicate detection using the “Bypass media duplicate upload prevention” permission.

No additional configuration pages or content types are added by the module.
