Mathematica 12.1 does not have a native way of handling S3 files, the AWSLink was removed.
Someone know where can I download it?
Today I use command line tool: https://stackoverflow.com/questions/8659382, but it does not work with Wolfram Cloud.
Where can I find the old AWSLink package with S3 interaction?

Take a look at this MSE post. Not sure if it work with the Wolfram Cloud though.
That's cool! Thanks for sharing. Now I know I need to discover how to use ExternalStorage`. S3 functions have been removed from AWSLink
I also notice we need to use aws2 CLI to connect to S3.
