+### Prerequisites
+If you want to follow along, you'll need the following:
+* An Azure subscription (If you don't have an Azure subscription, create a [free account](https://azure.microsoft.com/free/?WT.mc_id=azure-azuredevtips-azureappsdev) before you begin)
+* Create an [Azure Storage Account](https://docs.microsoft.com/azure/storage/common/storage-account-create?tabs=azure-portal)
+* Install [Az PowerShell modules](https://docs.microsoft.com/powershell/azure/install-az-ps) if not already
+* Use an authenticated account or service principal to connect to the storage account
+
+### Copy and execute below Powershell script to list all blobs in a storage account
+The time it takes to enumerate all blob objects will depend on the volume of your storage account. Output will be saved in a file named "blobs.txt" under the path you specify.
+
+#### Provide inputs by following the instructions
+```
+$subID = Read-Host "`n Enter your Subscription ID: "
+$rg = Read-Host "`n Enter the name of your Resource Group: "
+$sa = Read-Host "`n Enter the name of your Storage Account: "
+$path = Read-Host "`n Enter the path where you want to keep the generated report (blobs.txt): "
+$strAccountName = "$sa"
+$strAccountRG = "$rg"
+# Connect to Az  Account
+Connect-AzAccount
+# Choose subscription
+Select-AzSubscription -SubscriptionId "$subID"
+# create context
+$stCtx = New-AzStorageContext -StorageAccountName $strAccountName -StorageAccountKey ((Get-AzStorageAccountKey -ResourceGroupName $strAccountRG -Name $strAccountName).Value[0])
+# fetch containers
+$containers = Get-AzStorageContainer -Context $stCtx
+# placeholder to hold file list
+$array = @();
+# Property names to display
+$array += -join("Container", "; ", "Blob", "; ", "BlobType", "; ", "AccessTier")
+$array += "---------------------------------------------------------------------"
+foreach($container in $containers)
+{
+    # fetch blobs in current container
+    $blobs = Get-AzStorageBlob -Container $container.Name -Context $stCtx
+
+	# list all blobs and fetch properties
+	foreach($blob in $blobs)
+	{
+		$array += -join($container.Name, "; ", $blob.Name, "; ", $blob.BlobType, "; ", $blob.BlobProperties.AccessTier)
+	}
+}
+# Export to file
+
+$array | Out-File -FilePath "$path\blobs.txt" -NoClobber
+```
