powershell - Get-ChildItem error handling when using long file paths

I am trying to handle errors when scanning through folders. Let's say I have something like:

Get-ChildItem $somepath -Directory | ForEach-Object {
   if(error occurred due to too long path) {
        skip this folder then
   } else {
       Write-Host $_.BaseName
   }
}

When I do this I print the folders in $somepath until one of them is too long and then the loop stops. Even when using SilentlyContinue. I want to print even after reaching a folder that is too long.

If you can install a non-ancient PowerShell version (3.0 or newer), simply prepend the path with \? to overcome the 260-character limit for full path:

Get-ChildItem "\?$somepath" | ForEach {
    # ............
}
