向AppleScript脚本授予权限

我有一个简单的AppleScript，它应该删除下载文件夹中的所有内容，但最后传递的选定文件夹列表除外

tell application "Finder"
    delete (every item of "Downloads" of folder currentUser of folder "Users" of startup disk whose name is not in {"PreciousFolder"})
end tell

保存时，AppleScript返回以下错误：

---

您将删除文本字符串

“Downloads”

中没有意义的每一项。添加

文件夹

说明符

tell application "Finder"
    delete (every item of folder "Downloads" of folder currentUser of folder "Users" of startup disk whose name is not in {"PreciousFolder"})
end tell

或更短

tell application "Finder"
    delete (every item of (path to downloads folder) whose name is not in {"PreciousFolder"})
end tell

---

在文件夹说明符中，我的目的是删除下载文件夹中的文件和文件夹，不包括PreciousFolder及其内容。在这种情况下我需要文件夹或文件说明符吗？

文件夹

说明符指的是下载文件夹，而不是其内容<代码>每个项目都考虑文件和文件夹。
