我从互联网上得到了以下脚本,当我尝试运行它时,出现了错误。
#script
#unzip folder
$shell_app = new-object -com shell.application
$filename = "test.zip"
$zip_file = $shell_app.namespace("C:\temp\$filename")
#set the destination directory for the extracts
$destination = $shell_app.namespace("C:\temp\zipfiles")
#unzip the file
$destination.Copyhere($zip_file.items())
--- 错误消息

返回True。 - Keith Hill
