As of the 1.0 version of s3cmd, you can upload file larger than 5G.

Subject: [S3tools-general] Transferring files over 5G to AWS

Hello,

Is it possible to transfer a file bigger than 5G using s3cmd?  Somewhere I read that I can use command line arguments such as these:

x-amz-storage-class:REDUCED_REDUNDANCY s3_multipart_threshold:1073741824 s3_multipart_min_part_size:104857600"


Is that true?  Where can I find more info about this?  Tried s3cmd put --help but that didn't help.

Please help.  Thanks.
