S3是AWS提供的云存储服务，官网上S3的介绍是这样描述的：
Amazon Simple Storage Service (Amazon S3) 是一种对象存储，旨在通过 Internet 存储及访问任何类型的数据。
它非常安全，耐用性高达 99.999999999%，并且可扩展过去的几十万亿对象。S3 可用于备份和恢复、分层存档、用户主导型内容（如照片、视频、音乐和文件）、用于大数据分析的数据湖和数据仓库平台，或者作为无服务器计算设计的基础。
说起云存储，最容易想到的应用方式就是网盘，那么有没有工具可以让用户像使用网盘一样使用S3呢，今天我们推荐一款S3的客户端工具：S3Brower。

从图中可以看到，S3Browser的免费版本就提供了非常全面的功能，下面将简单的介绍S3Browser的使用。
账户设置
在使用S3Browser之前，需要在AWS的控制台界面中使用IAM服务为S3Browser创建专门的用户。为了提高安全性，可以用托管权限创建 S3桶的只读用户和S3的管理用户，也可以按照S3桶配置用户和权限。
如下图所示，可以在IAM中建立一个具有S3所有权限的S3Client用户。

添加S3管理用户2
添加IAM用户后，就可以在S3Browser中添加相应的Account。
在S3Browser中添加新账号
需要注意的是如果是Global的AWS账号那么Account Type选择Amazon S3 Storage，如果是中国区的AWS账号，Account Type需要选择Amazon S3 in China。
为了安全，还可以给账号设置一个密码，并且在传输时使用加密链接。
文件操作
完成账号设置后，就可以开始正式使用S3Browser了。S3Browser的使用和其他网盘客户端软件非常相似，可以批量的对文件进行上传、下载、剪切、复制、删除等各种操作。
需要特别指出是，S3Browser中的所有操作都支持断点续传，S3Browser会自动的进行文件拆分，上传时的块大小为16M ，下载时的块大小为100M。

S3 is a cloud storage service provided by AWS. The official S3 introduction describes it as follows:
Amazon Simple Storage Service (Amazon S3) is an object storage designed to store and retrieve any amount of data from anywhere.
It's highly secure, with durability of 99.999999999%, and can scale to store tens of trillions of objects. S3 can be used for backup and restore, tiered archiving, user-generated content (such as photos, videos, music, and files), data lakes and data warehouse platforms for big data analytics, or as the foundation for serverless computing designs.
When talking about cloud storage, the most common application that comes to mind is network drives. So is there a tool that allows users to use S3 like a network drive? Today we recommend an S3 client tool: S3Browser.

Main Features
S3 Browser Main Features
As you can see from the image, the free version of S3Browser provides very comprehensive features. Below is a brief introduction to using S3Browser.
Account Settings
Before using S3Browser, you need to create a dedicated user for S3Browser using IAM service in the AWS console interface. To improve security, you can create read-only users for S3 buckets and S3 management users with managed permissions, or configure users and permissions according to S3 buckets.
As shown in the figure below, you can create an S3Client user with all S3 permissions in IAM.
Add S3 Management User 1
Add S3 Management User 2
After adding the IAM user, you can add the corresponding Account in S3Browser.
Add New Account in S3Browser
Note that if it's a Global AWS account, select Amazon S3 Storage for Account Type. If it's an AWS China account, you need to select Amazon S3 in China for Account Type.
For security, you can also set a password for the account and use encrypted connections during transmission.
File Operations
After completing account setup, you can start using S3Browser officially. S3Browser works very similarly to other network drive client software, allowing batch operations for uploading, downloading, cutting, copying, deleting, and other file operations.
It's worth noting that all operations in S3Browser support resuming from breakpoints. S3Browser automatically splits files, with a chunk size of 16M for uploads and 100M for downloads.
