Thanks, but looks like just S3 support, without Glacier.

Please see the email.

@war59312: I'm sending you an email with a development version of WinSCP to the address you have used to register on this forum.

Thanks for your post.

This request is being tracked already:

I have raised a priority of S3 support. We are actually already working on this.

And if support S3, might as well support Amazon Glacier too.

Fuse does not handle aws s3 buckets with many files properly. I would be much better if the excellent WinSCP interface worked with S3.
