Question

How can I create a folder under a bucket using boto library for Amazon s3     I followed the manual  and created the keys with permission  metadata etc  but no where in the boto s documentation it describes how to create folders under a bucket  or create a folder under folders in bucket

S3 doesn t have a folder structure  But there is something called as keys    We can create  2013 11 xyz xls and will be shown as folder s in the console  But the storage part of S3 will take that as the file name    Even when retrieving we observe that we can see files in particular folder  or keys  by using the ListObjects method and using the Prefix parameter

Although you can create a folder by appending     to your folder name  Under the hood  S3 maintains flat structure unlike your regular NFS    var params                 Bucket   bucketName              Key   folderName                  s3 putObject params  function  err  data

There is no concept of folders or directories in S3  You can create file names like  abc xys uvw 123 jpg   which many S3 access tools like S3Fox show like a directory structure  but it s actually just a single file in a bucket
