Windows Azure Web Storage Explorer makes it easier for developers to browse and manage Blobs, Queues and Tables from Windows Azure Storage account. You'll no longer have to install a local client to do that. It's developed in C#.
Cloud Storage Manager provides you with an Explorer view of all your Azure Blobs. You can see details of each individual Blob, including Blob size, date the Blob was created and modified, as well as what Storage Tiering the Blob currently is in.
