S3Express : Command Line S3 Client and S3 Backup for Windows S3Express：适用于 Windows 的命令行 S3 客户端和 S3 备份

S3Express is a commercial S3 command line tool for Windows. Differently from S3cmd, S3Express is designed to run specifically on Windows, it is self-contained in one executable (s3express.exe) and does not require any additional libraries or software to be installed to run. It's very compact and has very small footprint: the entire program is less than 5MB. It's very easy to install on Windows servers, clients, desktops and laptop computers alike.
S3Express 是一个用于 Windows 的商业 S3 命令行工具。与 S3cmd 不同，S3Express 专为在 Windows 上运行而设计，它独立于一个可执行文件 (s3express.exe) 中，不需要安装任何额外的库或软件即可运行。它非常紧凑，占用空间非常小：整个程序不到 5MB。它非常容易安装在Windows 服务器、客户端、台式机和笔记本电脑上。

S3Express is developed and maintained by TGRMN Software, the company behind ViceVersa PRO, professional software for file backup, file synchronization and file copy on Windows.
S3Express 由 TGRMN Software 开发和维护，TGRMN Software 是ViceVersa PRO背后的公司，是 Windows 上用于文件备份、文件同步和文件复制的专业软件。

With S3Express you can list and query S3 objects using conditional filters, manage S3 objects' metadata and ACLs, upload files to S3 using multipart uploads and multiple concurrent threads, upload only new or changed files to S3 for automated backup (= incremental backup), delete multiple S3 objects, copy S3 objects, etc. using the Windows command line.
使用 S3Express，您可以使用条件过滤器列出和查询 S3 对象，管理 S3 对象的元数据和 ACL，使用分段上传和多个并发线程将文件上传到 S3，仅将新的或更改的文件上传到 S3 以进行自动备份（=增量备份），使用 Windows 命令行删除多个 S3 对象、复制 S3 对象等。

All operations in S3Express are multithreaded (fast), automatically retryable (network-failure resistant), and interruptible (= all commands can be stopped and restarted at any time). Connections to Amazon S3 are made using secure http (https), which is an encrypted version of the HTTP protocol, to protect your files while they're in transit to and from Amazon S3 storage servers.
S3Express 中的所有操作都是多线程的（快速）、可自动重试（抗网络故障）和可中断（= 所有命令都可以随时停止和重新启动）。与 Amazon S3 的连接是使用安全 http (https)（HTTP 协议的加密版本）建立的，以在文件与 Amazon S3 存储服务器之间传输时保护您的文件。
