S3 management tools

Olga Weis

Popularity of Amazon S3 has been increasing ever since it was introduced, partially because you only pay for the hosting you use, partially because the amount of storage and bandwidth depends entirely on your needs, there is no limitation to it. The data is organized in so-called buckets, and AWS Console is the default S3 bucket browser provided by Amazon. It allows you to connect to Amazon, upload files to S3, manage their properties and perform other operations.

There is also a number of tools that work as Amazon S3 file manager, most popular among them being Commander One, CloudMounter, Transmit, Dragon Disk and S3 Browser.

First thing you need to do to use such a third party S3 file manager is to obtain credentials for Amazon connect – Access Key and Secret Key. They can be generated either for our root account or an IAM user who will only get specified permissions. We’ll take an example of root account credentials:

  1. Click your account name on the AWS Console, in the drop down menu choose Security Credentials.

  2. In the screen displayed go to Access Keys section and click “Create New Root Key” button.

  3. A window will be displayed with your Access Key, make sure to download the credentials – Amazon does not store such information. You’ll need both keys to use the Amazon S3 browser you choose to upload file to S3 and do other stuff.

Okay, now the applications

Commander One

Amazon S3 client Mac users will appreciate. Basically it is a file management solution for OS X that can mount Amazon S3 account on Mac so you can access and manage data stored there as if it were on a local drive. Thanks to the dual pane interface you can easily ‘drag-and-drop’ files and folders from one location to another.


Ideal for those who need a single point of access to multiple cloud storage services, this Mac S3 browser can mount your Amazon S3, Windows OneDrive, Google Drive, Dropbox accounts on Mac and connect you to remote FTP and WebDAV servers.


This is another Amazon S3 browser Mac owners can look at. It uses Quick Look on supported remote files and allows you to organize your remote data in folders.

Dragon Disk

The main advantage of this object manager for S3 is that it works across platforms – Windows, Mac OS X and Linux. The app has a dual pane interface where one pane displays files and folders stored locally, and the other one – S3 buckets.

S3 Browser

This client is meant only for Windows. Apart from enabling you to perform basic management operations such as S3 file upload, it allows you to set up object’s life cycle and enables object versioning.
