Hello,
Just as a short introduction, I am a windows/cloud engineer currently working with AWS workload on a daily basis.
I'd be happy to show you how to download your objects/files from an S3 bucket in a few different ways (fastest is through the cmd line, but i can also help you set up a GUI based software too).
Otherwise, I can download the files for you and upload it to dropbox and provide you with a link.
If you are happy for me to do this for you, please feel free to chat with me and I'll get started on this :)
Thank you
