I am looking for a program that
- can upload a folder, its sub-folders and recursively, to an Amazon S3 bucket. It should be gratis (unlike S3Express) at least for personal use
- can upload large files (say over 50 GB, unlike S3Fox, which only allows file uploads/downloads upto 2GB).
- works on Windows
I don't want to have to go through some EC2 instances, but directly upload from Windows to Amazon S3.
