Problems Setting Up Digital Downloads...

Okay, I am setting up two different albums for sale as digital downloads. My two albums are 635MB and 748 MB. The MAX upload file size is 64MB. Can I manually upload the albums in my cPanel or Filezilla. I definitely need to be able to upload files bigger than 64 MB. I am using Amazon S3 if that helps. Please advise how I can upload bigger than 64 MB files.
