Connect to Amazon S3 from Windows

Browse and transfer Amazon S3 buckets from a Windows desktop app. IAM access key setup, a least-privilege policy and storage class notes.

Get your keys

  1. In the AWS console, open IAM and pick (or create) a user for yourself.
  2. Under Security credentials, create an access key for CLI/third-party use.
  3. Copy the Access Key ID and Secret Access Key.

Give the user only the S3 permissions it needs. A practical starting policy allows s3:ListAllMyBuckets plus full access to the specific buckets you work with; avoid attaching account-wide admin just to browse files.

Connect

  1. Add a new connection and choose the Amazon S3 preset.
  2. Paste the keys. If you already use the AWS CLI, the app can also import the profiles from your existing AWS config files instead.
  3. Connect. The app resolves each bucket’s region automatically, so buckets from every region show up in one connection.

Good to know

  • No endpoint to type: the preset uses AWS’s regional endpoints automatically and follows each bucket to its home region.
  • Storage classes are visible in the file table. Objects in Glacier classes need a restore before download; standard and infrequent-access classes download directly.
  • The app’s versioning browser, lifecycle editor, policy editor and CORS editor map to the same S3 features you would otherwise manage in the AWS console.
  • Share links that expire respect your IAM permissions and work for specific object versions too.
