  • Monitor the CLI output for progress information and any possible errors.

Note: The AWS CLI is a powerful option for those familiar with command-line tools and looking to automate uploads through scripts.

Conclusion: Ideal for automated and larger file uploads, the AWS CLI provides a reliable and scriptable method.

Method 3: Using Amazon S3 Transfer Acceleration ✈

  • Enabled via the AWS Management Console, S3 Transfer Acceleration speeds up the transfer of files over long distances.
  • To use this feature, enable it on your bucket under the bucket properties.
  • Upload files as you normally would, and AWS will route the data through their optimized network paths.

Note: This method incurs additional costs and is ideal when reduced upload times are crucial for large or time-sensitive files.

Conclusion: S3 Transfer Acceleration is valuable for businesses and individuals who need fast uploads across continents.

Method 4: Using S3 Multipart Upload ⚡

  • Consider this method for files larger than 100MB, which splits the file into smaller parts for upload.
  • Several tools and SDKs, like the AWS SDK for Python (boto3), support multi-part uploads.
  • The process includes initiating the upload, uploading the parts, and completing the multi-part upload operation.

Note: Requires programming knowledge or a tool with built-in support for multi-part uploads.

Conclusion: Multipart upload is most effective for very large files and unstable connections, as you can retry individual part uploads.

Method 5: Using Commander One for macOS 🍏

  • Download and install Commander One, an app for macOS that makes managing files between your computer and cloud storage, including Amazon S3, a breeze.
  • Open the app and connect to your Amazon S3 account by adding it as a new connection. You’ll need your AWS access and secret keys here.
  • Navigate to the S3 bucket where you wish to upload your file.
  • Drag and drop the large file from your Mac to the designated S3 bucket in Commander One’s interface.
  • The app automatically manages the upload process, even utilizing multi-part uploads for larger files if necessary.

Note: Commander One offers an intuitive graphical interface that eases the process for users who prefer not to deal with command-line tools.

Conclusion: Commander One is an excellent choice for macOS users looking for a simple and efficient way to handle large file uploads to S3.

Method 6: Using Cloud Storage Browsers 🌥
