Makes a copy of Windows Spolight images for your lockscreen,
and saves them to your $env:USERPROFILE\Pictures\Spotlight directory.
If the directory doesn't exist, it is created. Any image larger than
100 KB is copied, as some images in this folder are not wallpaper.
Also, files are renamed with date-stamp, along with first 8 charaters
of filename. This is just to help in sorting.

$ProfileDir = $env:USERPROFILE
$SourceDir = "$ProfileDir\AppData\Local\Packages\Microsoft.Windows.ContentDeliveryManager_cw5n1h2txyewy\LocalState\Assets"
$DestinationDir = "$ProfileDir\Pictures\Spotlight"

If ( -Not (Test-Path -LiteralPath $DestinationDir)) {
  New-Item -ItemType Directory -Force -Path $DestinationDir
}

$SpotFiles = (Get-ChildItem -LiteralPath $SourceDir |
    Where-Object {$_.Length -ge 100KB})

Foreach ($SF_Item in $SpotFiles) {
  $TimeStamp = $SF_Item.CreationTime.ToString('yyyy-MM-dd_HH-mm-ss')
  $NewFileName = '{0}_-_{1}.jpg' -f $TimeStamp, $SF_Item.Name.SubString(0, 8)
  $FullNewFileName = Join-Path -Path $DestinationDir -ChildPath $NewFileName
  Copy-Item -LiteralPath $SF_Item.FullName -Destination $FullNewFileName
}
