A. I had a large folder of virtual machines I had exported. Each folder was a separate machine, and I wanted to run a script to import each VM in the folder. The first step was to use PowerShell to create the list of folders. To do that, I needed to list all child items in a path then check if the item is of type directory, as shown below.
PS E:\Virtuals> b




    Directory: E:\Virtuals




Mode                LastWriteTime     Length Name

The next step is to pass this output to another command. For example, below I just pass it to a command to list the fullname of the directory. You could use any function you need to.
PS E:\Virtuals> Get-ChildItem e:\virtuals | Where-Object { $_.Attributes -band  [System.IO.FileAttributes]::Directory } | ForEach-Object {Write-Host $_.FullName}
