HowTo: Connect to a bucket with S3 Browser

In addition to uploading or downloading files using Portal, if you need to transfer large files, we recommend using commonly used third-party software such as S3 Browser or Cyberduck to manage files in COS buckets.

  • S3 Browser is a simple and easy to use Amazon S3 Windows client that provides a simple web service interface to store and retrieve data from anywhere on the web.
  • The S3 Browser Free Edition is for non-commercial use only. For details, see S3 Browser official website.
