Blobs downloading from azure blob container's folder

问题

When I am downloading blobs from Azure:

$BlobName = "20171019/fac/file.jpg" 
Get-AzureStorageBlob -Container $ContainerName -Blob $BlobName

By using above command I am getting only single file.

Get-AzureStorageBlob -Container $ContainerName

By using this I am getting all blobs from container.

20171019 is folder name in container, then sub folder fac.

My requirement is to download all blobs from Fac folder.

We should use this command Get-AzureStorageBlobContent to download Azure storage blobs.

If you want to download all blobs in that container, we can use foreach to do it, like this:

$RGName = "your resource group name"
$SAName = "your storage account name"
$ConName = "your container name"
$key = "your storage account key"
$Ctx = New-AzureStorageContext -StorageAccountName $SAName -StorageAccountKey $Key
$List = Get-AzureStorageBlob -prefix "20171019/fac/" -Container $ConName -Context $Ctx
$List = $List.name
foreach ( $l in $list ){
Get-AzureStorageBlobContent -Blob $l -Container $conname -Context $ctx
}

Here is the result:

Thank you for Gaurav's suggestion, I add -perfix to that script.

Besides Azure PowerShell, you can also try AzCopy, which has even better performance.

AzCopy /Source:https://myaccount.blob.core.windows.net/mycontainer/20171019/fac /Dest:C:\myfolder /SourceKey:key /S
