How to Upload Files and Folders on Amazon S3?

You can upload file(s) from local system to Amazon S3 account using Bucket Exolorer, process will be in queue .

Bucket Explorer never re-uploads a file which is not changed (contents are same). Bucket Explorer checks the hash of the local file with Etag value of S3 file and if the value is same, the file is skipped from upload process. This is called as Name and Hash checking for already exist file.
Bucket explorer provides much faster checking for uploading file(s), by comparing it with Name and Size. As if Uploading file(s) already exist on the S3 then Bucket Explorer will check the name and the size of file(s). If the file found identical then it will not upload the file(s).

Bucket Explorer adds an extra header 'bucketexplorer-filelastmodifieddate' while it uploads file(s) on S3. The value of this header is the Last Modified Date of uploaded file . You can check this header value to know when the file(s) have been modified on local using Object Property window Or Update Metadata window.

 Bucket Explorer preserves ACLs and Metadata while overwriting  file(s) on Amazon s3.
