What is AWS S3 Files and how do I use it?

Mount S3 buckets as local filesystems using AWS CLI or SDK. Works with standard POSIX ops — `ls`, `cat`, `grep` direct on buckets.

Does S3 Files work with existing code?

Yes — any app using file I/O (open(), read()) treats S3 like disk. No rewrites needed.

Preview in select regions, One Zone. GA soon; check AWS console.

Type 'ls' on a petabyte S3 bucket. Instant. No downloads, no SDKs. AWS just erased the line between cloud storage and your hard drive.
