Sometimes, you want to look for an archived file or PDF in Azure Storage. You can do that via the Azure Portal - Storage Accounts - <name of storage account> - Blob Service - Containers.
However, if you do not have access to the Azure Portal or want to use the Azure Service Bus Explorer from your local computer/server, you can download the application here: https://azure.microsoft.com/en-us/features/storage-explorer/
You will need the connection string from the Storage Access to connect.
