I have thins link below, and when I try to acess it it appears an xml file saying \"Acess denied\".
And I need to go to aws managment console and make this part-00
This should give you an idea:
import boto.s3
conn = boto.s3.connect_to_region('us-east-1') # or region of choice
bucket = conn.get_bucket('myFolder')
key = bucket.lookup('uploadedfiles/2015423/part-00000')
key.set_acl('public-read')
In this case, public-read
is one of the canned ACL policies supported by S3 and would allow anyone to read the file.
