What is Amazon S3 Files exactly?

It's a mounted NFS view of your S3 bucket—full file semantics, no data movement, bidirectional sync.

Does Amazon S3 Files work with existing S3 buckets?

Yes, zero migration. Mount any bucket in supported regions.

Not fully—it's S3-optimized. Use for object-backed files; EFS for pure hot data.

AWS dropped S3 Files, killing the object-vs-file storage nightmare. Your Unix tools now run natively on S3, data stays put, and AI agents thrive.
