FileLu S5 Object Storage
S3-compatible object storage without complexity, request fees, or separate storage silos.

FileLu S5 is S3-compatible object storage built for simplicity, performance, and scalability. It works with AWS CLI, Rclone, Restic, Kopia, Proxmox, Duplicacy, Duplicati, S3 Browser, FileBrowserGO, Synology Hyper Backup, and many other S3-compatible tools.

Buckets appear directly inside your FileLu Web UI, Mobile App, FileLuSync, FTP, and WebDAV. One account, one storage, all tools.

Connect to FileLu S5

FileLu S5 works like Amazon S3, so you can connect with your favorite tools right away. It is available to all Free plan users. Premium users also get Presigned URLs for easy sharing.

What is Object Storage?

FileLu S5 is powered by object storage. Any folder can be enabled as an S5 Bucket, keeping the familiar FileLu UI while acting as an S3-compatible bucket.

  • Works as normal folders until enabled.
  • Once enabled, the folder becomes an S3-compatible bucket.
  • Supports unlimited objects with unique keys.
  • Supports system and custom metadata.
  • Supports file tagging for organization and search.
  • Supports configurable CORS for cross-origin access.
  • Optimized for multipart uploads and large objects.
  • Compatible with Secure-Solo-Cipher Encryption SSCE.
  • Built for global scalability and fast delivery.

Tip: To create a new bucket, go to the FileLu UI, click Edit Folder, enable S5 Bucket, then click Save. You can also create buckets directly with AWS CLI, Rclone, s3cmd, or SDKs.

ACLs & Permissions

FileLu S5 supports bucket and object ACLs through AWS CLI, SDKs, and compatible tools. Permissions are simplified for safety.

  • Bucket Owner: Full access, including create, upload, download, delete, ACL, and policy.
  • Shared Users: Can list, upload, replace, and download, but cannot delete.
  • Granularity: FULL_CONTROL is supported. Use bucket policies for advanced rules.

For advanced use cases such as read-only access, IP restrictions, or referer checks, define a Bucket Policy.
