Directory List in amazon S3 with AWS SDK

Question

I am trying to list folders in S3:

string delimiter = "/"; folder = "a/"; ListObjectsResponse r = s3Client.ListObjects(new Amazon.S3.Model.ListObjectsRequest() { BucketName = BucketName, Prefix = folder, MaxKeys = 1000, Delimiter = delimiter }); 

and I expect a list of directories such as:

 a/Folder1 a/Folder2 .... a/FolderN 

but my actual result is only 1 object: 'a1'

Answer 1

Folders are not considered objects in S3.

Instead, I need to read the string [] property of CommonPrefixes , which has my subfolders
