改进后的脚本：

#文件夹和输入文件件
$fromDir='D:\.weibo_chat.tar\txt\'
$saveToDir='D:\.weibo_chat.tar\txt\合并后的文本\'




if(-not (Test-Path $fromDir)){
  echo '请输入正确的文件所在路径！'  
  return
}

if(-not (Test-Path $saveToDir)){
  mkdir $saveToDir
}

function funcCombinFiles($fileDir, $destFile)
{
    echo '' > $destFile
    $fileList = Get-ChildItem -Depth 1  $fileDir -r  *.txt

    Foreach($file in $fileList)
    {
       get-content $file.fullname >> $destFile
       echo '' >> $destFile
    }

}

#输出文件名
$now= Get-Date -Format 'yyyy-MM-dd-HH-mm-ss'
$fileName =$saveToDir+$now+'.rtf'

funcCombinFiles $fromDir  $fileName
