Frequently Asked Questions
Where are media files stored?
Media files are stored in /wp-content/uploads/ organized by year and month folders (e.g., /uploads/2026/01/).
Can I change the upload folder structure?
Yes, go to Settings → Media to change the folder organization. However, changing this doesn’t reorganize existing files.
How do I bulk delete unused media?
Use the “Unattached” filter in Media Library, or plugins like Media Cleaner to find and remove unused files safely.
Can I replace an image without changing the URL?
Not by default. Use the “Enable Media Replace” plugin to replace files while keeping the same URL and links.
Best Practices
- Name Files Descriptively: Use keywords in filenames
- Always Add Alt Text: For accessibility and SEO
- Organize Regularly: Don’t let the library become cluttered
- Backup Media: Include uploads folder in backups
- Clean Unused: Periodically remove unused files
