Increments a number in a file path until the path is unique. Got tired of writing this every time I need it.

Make-UniquePath.ps1

function Make-UniquePath {
    param([string]$path)

    $ptemp = $path
    $inc = 1;
    $ext = [IO.Path]::GetExtension($path)
    while (Test-Path $ptemp) {
        $tmp_ext = [String]::Concat("-",$inc.ToString("D2"),$ext)
        if ([String]::IsNullOrEmpty($ext)) {
            $ptemp = [String]::Concat($path,$tmp_ext)
        } else {
            $ptemp = $path.Replace($ext,$tmp_ext)
        }
        $inc++
    }
    return $ptemp
}
