How to compare two Amazon S3 Buckets?

Bucket Explorer comparer allows you to compare two Amazon S3 buckets as well as files using compare contents (in the case of Bucket and Folder selection) and compare files options. It also allows you to copy and move content between the same buckets as well as different account’s buckets

Bucket Explorer provides you with two ways to perform comparison:
  1. Compare with Name and size - This option is used to get fast comparison result. It shows the result of comparison on the basis of file size.
