I am having some trouble figuring out how to access a file from Amazon S3. Lets say that the bucket that the file lives in is BUCKET_NAME, the file is FIL
BUCKET_NAME
FIL
Perhaps not what the OP was after, but for those searching the URL to simply access a readable object on S3 is more like:
https://.amazonaws.com//
Where is something like s3-ap-southeast-2.
s3-ap-southeast-2
Click on the item in the S3 GUI to get the link for your bucket.
