I have a container named "pictures", and have some folders named "Folder1", "Folder2" inside of it. So files of my blob will be addressed like this "http://optimus.blob.core.windows.net/pictures/Folder1/IMG123.png". Using the below C# code to delete the files inside folders, 

CloudStorageAccount storageAccount = CloudStorageAccount.Parse(*AzureConnectionString*);

CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();

CloudBlobContainer container = blobClient.GetContainerReference("pictures");

var blobs = container.ListBlobs("Folder1", true);
foreach (var blob in blobs)
{
  container.GetBlockBlobReference(((CloudBlockBlob)blob).Name).DeleteIfExists();
}

after deleting all those files in "Folder1" it will be empty. I m trying to delete the empty folder, but can't get a way to do it. Is it possible to delete the folder(s)? Any help will be much appreciated. Thanks in advance.

For Azure Blob Storage, there isn't really a 'folder' object. 'Folders' are actually just blob name prefixes - the '/' character being used to separate 'folders' is a convention in blob naming, not a requirement. So, you don't have to worry about it - as long as there are no blobs with the "Folder1" prefix, then you're fine.
