Upload and Download files from Azure Blob Storage using Connection String

It's important to know that the blob storage is case-sensitive. That means you can upload multiple files with the same name but different casing. Downloading all available files is available by using foreach and Get-AzStorageBlobContent.

# 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
}

If you want to overwrite existing content, you need to use the Force switch. Otherwise, you will be prompted for every file on the disk. To upload the file, you have to use Set-AzStorageBlobContent. 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.

# upload file to blob storage
$SourceFile = "$PSScriptRoot\Downloads\test.PDF"
# upload file to blob storage but without changing the name
Set-AzStorageBlobContent -File $SourceFile -Container $ContainerName -Context $Context
# upload file to blob storage and change the name
$DestinationFile = "test1.pdf"
Set-AzStorageBlobContent -File $SourceFile -Container $ContainerName -Context $Context -Blob $DestinationFile

And that's it. You now know how to upload and download files from Azure Blob Storage.
