The first thing we need to do is to install Az.Storage<\/strong> module, which in turn will also download Az.Accounts<\/strong> module.<\/p>\n\n\n\n

Install-Module -Name 'Az.Storage' -Force -Verbose -Scope CurrentUser<\/pre>\n\n\n\n
I always like to use Force and Verbose parameters. Force makes sure it redownloads everything that is required and makes sure it’s up to date. Verbose adds a bit more information about what is happening. Install-Module tends to go slow, and things can look like nothing is happening. Once we have our modules installed, we need to define ConnectionString<\/strong> and ContainerName<\/strong> and use New-AzStorageContext<\/strong>. We then pass the Context variable to Get-AzStorageBlob<\/strong> to get a list of available files on the storage.<\/p>\n\n\n\n
\"\"\/<\/figure>\n\n\n\n

# define data
$DestinationFolder = \"$PSScriptRoot\\Downloads\"
$ContainerName = \"eclcontainer\"
$ConnectionString = \"DefaultEndpointsProtocol=https;AccountName=test;AccountKey=rrandomKeymXwY8\/+dPIHH8=;EndpointSuffix=core.windows.net\"

# connect to blob storage
$Context = New-AzStorageContext -ConnectionString $ConnectionString

# list current content
$ContainerStorage = Get-AzStorageBlob -Container $ContainerName -Context $Context
$ContainerStorage | Format-Table<\/pre>\n\n\n\n
<\/p>\n\n\n\n
It’s important to know that the blob storage is case-sensitive<\/strong>. That means you can upload multiple files with the same name but different casing. Downloading all available files is available by using foreach<\/strong> and Get-AzStorageBlobContent<\/strong>.<\/p>\n\n\n\n
<\/p>\n\n\n\n
# go thru each file and download
foreach ($File in $ContainerStorage) {
    $Destination = \"$DestinationFolder\\$($File.Name)\"
    Get-AzStorageBlobContent -Container $ContainerName -Blob $File.Name -Context $Context -Destination $Destination -Force
}
<\/pre>\n\n\n\n
If you want to overwrite existing content, you need to use the Force<\/strong> switch. Otherwise, you will be prompted for every file on the disk. To upload the file, you have to use Set-AzStorageBlobContent<\/strong>. You can upload a file with the same name as it has on the drive by not providing the Blob parameter or providing it and giving it a different name on the storage.<\/p>\n\n\n\n
<\/p>\n\n\n\n
# upload file to blob storage\n$SourceFile = \"$PSScriptRoot\\Downloads\\test.PDF\"\n# upload file to blob storage but without changing the name\nSet-AzStorageBlobContent -File $SourceFile -Container $ContainerName -Context $Context\n# upload file to blob storage and change the name\n$DestinationFile = \"test1.pdf\"\nSet-AzStorageBlobContent -File $SourceFile -Container $ContainerName -Context $Context -Blob $DestinationFile<\/pre>\n\n\n\n
<\/p>\n\n\n\n
And that’s it. You now know how to upload and download files from Azure Blob Storage<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":"
