I came across the newly developed app in AppExchange named Drag, Drop & Upload Files to Amazon S3 for this.Am using the same and its very easy to use and having advanced features like you can delete/view your files from salesforce, and also provide some additional customization .

If you have been using Salesforce for any length of time, you have probably wanted to attach large and multiple files at one time. Now you can! In standard salesforce, you can attach and only upload files up to 25MB size one at a time.

This App provides you the facility to associate multiple files to a record in one go and without any size restriction.
Please have look:
S3- Link is FREE App for Salesforce - Amazon S3 Connector. Its also available on Appexchange. 
  1.     Attach file related to any Salesforce object on Amazon.
  2.     Ulimited free storage for one year.
  3.     Multiple file uplaod.
  4.     No file size limit for upload.
  5.     File access control capabiliy.
  6.     Track file downloads by users.
  7.     File exlorer capability.
