Which of my MP3 directories don't have a Folder.jpg file?
There’s probably a better way to do this, but here’s what I came up with in a couple of minutes…
Get-ChildItem $mp3_root -recurse -include *.mp3 |
Split-Path -parent |
Get-Unique |
ForEach-Object {
$folder_jpg = Join-Path $_ Folder.jpg ;
if (-not (Test-Path $folder_jpg)) { $_ + ": missing Folder.jpg" }
}
