Amazon S3 doesn't natively support mounting S3 buckets as drives on Windows EC2 instances as easily as it does on Linux-based instances. However, there are some workarounds and third-party tools that can assist in achieving a similar effect.

One way to achieve this is by using the AWS Systems Manager Session Manager and S3 integration. This allows you to interact with S3 via the AWS Management Console directly from a browser-based shell without mounting the bucket as a drive. Here's a general outline:

  1. AWS Systems Manager Session Manager: You can establish a session with your Windows EC2 instance using AWS Systems Manager. Once connected, you can use the AWS Command Line Interface (CLI) to interact with your S3 bucket.

  2. AWS CLI: With the AWS CLI installed on your Windows EC2 instance, you can use commands like aws s3 cp, aws s3 sync, etc., to interact with your S3 bucket. This method doesn’t involve mounting the S3 bucket as a drive but allows you to perform various operations on S3.

If you specifically require a mounted drive-like functionality, third-party tools like TntDrive or Expandrive might have limitations, as you've experienced. Exploring different tools or applications that offer S3 bucket mounting for Windows might help, but it's essential to consider their limitations and functionalities, especially regarding file size limitations.

As for open-source libraries or PHP-based solutions for mounting S3 buckets as drives on Windows instances, I'm not aware of any specific libraries or scripts that provide this functionality directly. However, you could explore various open-source projects or libraries that interact with the AWS SDK for .NET or other AWS SDKs compatible with Windows environments. These might not provide direct drive-like mounting but can offer programmatic access to interact with S3 buckets from your Windows EC2 instance.

Remember to carefully evaluate any third-party tools or scripts for security, compatibility, and reliability before implementing them in your production environment.

  • I already have AWS CLI installed and can ls the s3 bucket, Can you list down useful commands for this option like how to upload and how to download a directory ..

    thank you.


Take a look at Amazon S3 File Gateway

Q: What protocols does Amazon S3 File Gateway support?

Amazon S3 File Gateway supports Linux clients connecting to the gateway using Network File System (NFS) versions 3 and 4.1, and supports Windows clients connecting to the gateway using Server Message Block (SMB) versions 2 and 3.

Instructions for creating the SMB share are at

And how to mount it

  • Thank you so much for the Answer,, this looks like a cool option for our frequent data access workloads,.Will try this, However, I am looking for an option where we can save backup files like Dropbox, or Google Drive kind a way, So backup can save and forget, Only access if the backup need to be taken for restoration purpose,

    There is an Hourly price is added to the Amazon S3 File Gateway support, so might be not applicable for my use case.

  • You're welcome. And I agree it's not a cheap solution, but if you really need to access a bucket as a drive letter or a UNC path then it's the best (and I think the only "official") option.

    You may be able to reduce costs by having lambda functions that only make this active during business hours for instance. Even outside of those t8mes it doesn't preclude you from running commands like aws s3 cp, aws s3 sync and so on.
