Better asynch non-locking copy massive files

[Jeffrey Scott Humphreys]

Start-BitsTransfer -Source https://server01/servertestdir/. -Destination c:\clienttestdir\

Run it as job? Then show status in GUI? Probably max 3 jobs, same as in Windows Explorer.

    $BasePath = $args[0]

    $files = Get-ChildItem -File -Recurse -Path "$($BasePath)\$($Filename)" -ErrorAction SilentlyContinue

    foreach ($file in $files)

Found this online (no credits given).

Testing.

        Write-Host "`$MeaningfulPartOfSourcePath = $MeaningfulPartOfSourcePath"

        if ((Test-Path -LiteralPath $fileOrDirectory.FullName -PathType Container))
        {
            # For cases where directories are empty, we still want to move them over.
            Write-Host "Creating directory: $NewlyConstructedTargetPath"
            New-Item -Path $NewlyConstructedTargetPath -ItemType Directory -Force|Out-Null
        } else {
            Write-Host "Copying file to: $NewlyConstructedTargetPath"
            # We want to use Move-Item because of space concerns when moving to the same spindle.  Huge moves of many files and directories could run out of space with Copy-Item
            Move-Item -LiteralPath $fileOrDirectory.FullName -Destination $NewlyConstructedTargetPath -Force|Out-Null
        }
    }
    Write-Host "`$SourcePath = $SourcePath"

    # This deletes the source
    Remove-Item -LiteralPath $SourcePath -Force -Recurse -ErrorAction SilentlyContinue|Out-Null
}

Much better. Moves all directories as well.

Great progress. However, issues with migrating drives vs. just moving and replacing last folder ("from", "to"). So setting up flags.
