Frequently Asked Questions (FAQ)

Q: Which S3 providers are supported?

A: S3 File Manager supports Amazon S3 and any S3-compatible storage providers. This includes Cloudflare R2, Backblaze B2, MinIO, Wasabi, DigitalOcean Spaces, Linode Object Storage, and custom private S3 installations.

Q: Is App Sandboxing enabled?

A: Yes! The application is fully sandboxed in accordance with Apple's App Store guidelines. This guarantees that the application can only access folders you choose (for uploads/downloads) and cannot inspect other areas of your hard drive.

Q: How are credentials stored?

A: All credentials are saved locally in the app's encrypted database and Keychain. They are never transmitted to us or any third party. Connections are made securely over HTTPS directly to your S3 endpoints.

Q: What should I check if my bucket content is not loading?

A: Please make sure that:

Your Access Key and Secret Key are correct.
The Endpoint URL is fully qualified and matches the provider's S3 API region structure.
Your S3 bucket policies/CORS settings allow the connection.
