What it does
S3Express is a self-contained Windows utility for S3-compatible storage with conditional filters, multipart uploads, retries and object-management operations.
S3Express is a self-contained Windows command-line client for S3 and compatible storage. Configure the storage authorization, then use put with local files and a destination bucket. Selection flags distinguish missing objects and newer timestamps; recursive filters help retain the intended scope in a batch job. Treat deletion flags separately: purge removes S3 objects missing locally, while move or localdelete can remove source files. ACL and metadata commands can also change object access. The software offers a fully functional twenty-one-day trial; it does not supply the destination bucket or its permissions.
