Miller Media Server File Import

Miller Media Server File Import lets WordPress administrators browse files already on the server and import them directly into the Media Library — no need to download and re-upload.

This is useful when:

• You've migrated files via FTP/SFTP and need to register them in WordPress
• A developer has placed assets on the server that need to be in the Media Library
• You have files in a non-standard location that should be accessible through WordPress

Features:

• AJAX-powered file browser with breadcrumb navigation
• Select individual files or use "Select All" to import in bulk
• Duplicate detection — files already in the Media Library are flagged
• Copy or move files from outside the uploads directory
• Restrict browsing to a configurable root directory (defaults to wp-content)
• Limit allowed file types via settings
• Full REST API for programmatic access
• Works with any user role that has the upload_files capability

Security:

• Path traversal protection via realpath() boundary checks
• MIME type validation using WordPress core functions
• Capability checks on all endpoints (upload_files for browse/import, manage_options for settings)
• CSRF protection via WordPress REST API nonces
