A doubt using Rest API for windows azure storage (Delimiter)

Question

Hi,

I have a container with blobs and a folder containing blog. Now If I use this URI, http://myaccount.blob.core.windows.net/mycontainer?restype=container&comp=list&delimiter=/

I was expecting the output to have all the blob names under the container and the folder name alone. But to my surprise all I got is blob names. Can someone please tell me whether there is anything wrong, or should I change the query ? Thanks in advance.

Answer 1

Your expectation would seem realistic given the documentation.  It might be worth using some third-party storage visualization tool such as Cloud Storage Studio to verify the "folder" structure is what you think it is.

Answer 2

Can you share some of the code you're using and what the response looks like?

Answer 3

Hi,

URL for listing blobs that you're using looks fine. Here is one thing that you may want to look into the response received from Azure Storage.

You will not get a separate node for folders i.e. all folders and blobs are contained "Blobs" node. The way to differentiate between a folder & a blob is by looking for <BlobPrefix> node in the response XML. This will contain the folders while the <Blob> node will contain the actual blob.
