Download multiple files by BITS

Last time we looked at BITS we saw how to transfer a single file. The example in the help file doesn’t work in my environment so this is what I came up with as a work around

Import-Module BitsTransfer -Force            
            
$computername = "WebR201"            
$destination = "c:\source\transfer\"            
            
Get-WSManInstance -ResourceURI wmicimv2/* -Enumerate -Dialect WQL `
 -Filter "SELECT * FROM CIM_DATAFILE WHERE Drive='C:' AND Path='\\Transfer\\' " `
  -ComputerName $computername  |            
foreach {            
             
$name = Split-Path -Path $($_.Name) -Leaf            
$source =  "http://webr201/transfer/$name"            
Write-Host "Transferring $source to $destination"            
            
Start-BitsTransfer -Source $source -Destination $destination             
            
Test-Path -Path ($destination + $name) -Verbose            
}

Import the module

The use WMI over WSMAN cmdlets to find the files in the folder – this assumes that I know the physical path to the virtual directory – within my enterprise there’s no reason why I shouldn’t.

For each of the files I create the URL to the file – use Write-Host to put out a message and then use Test-Path on the destination folder to determine that it has arrived
