S3 Browser

S3 Browser is a graphical interface for managing S3-compatible storage on Windows, similar in functionality to FTP clients.

You can download the latest version of S3 Browser from the developer's website.

Configuration

To connect to the storage, you will need the S3 Parameters available in the bucket Settings:

1. Open the connection setup wizard by going to Accounts > Add new account.

2. Fill in the connection details:

• Display name: The name for this connection account (you can set any name you prefer).

• Account type: Select S3 Compatible Storage.

• REST Endpoint: s3.hostman.com

• Access Key ID: <Your Access Key>

• Secret Access Key: <Your Secret Access Key>

3. Click on advanced settings at the bottom left.

4. Make sure to select AWS Signature V4 or V2 versions and Path style.

5. Click Close, then complete the account setup by clicking Add new account.

Once connected, you will see all existing buckets created on your Hostman account.

Working with S3 Browser

Let’s go over basic operations for working with the storage via S3 Browser. 

Creating a new bucket

To create a new bucket:

1. Click on New bucket. 
2. Enter the bucket name.
3. Click Create new bucket.

Uploading objects

To upload files or directories:

1. Click Upload.
2. Select Upload file(s) or Upload folder(s).
3. Select files or directories from your computer.

You can also upload files using drag&drop.

Downloading objects

To download files or directories in S3 Browser:

1. Select the file or directory and click the Download button.
2. Choose the folder where you want to save the downloaded file or directory.
3. The download will start automatically.

Note that large files are downloaded in parts and, upon completion, the file is reassembled on your device from the downloaded fragments.

Deleting objects

To delete files or directories:

1. Select the file or directory.
2. Click Delete. 
3. Confirm deletion.

Managing Interrupted Multipart Uploads

S3 supports multipart uploads, which split a file into multiple parts (chunks) and upload them in parallel, speeding up large file transfers and improving fault tolerance.

If a multipart upload is interrupted, file fragments won’t appear in the bucket but will still occupy disk space on the server. To view incomplete uploads, go to Tools → Uncompleted Multipart Uploads.

Here you can see all the unfinished uploads. To delete, select an upload and click Abort Selected.

The upload will no longer take space in the bucket.
