PowerShell脚本，该脚本使用If/Else的测试路径，如果为False，则If/Else不工作

完全公开，我对使用Powershell非常陌生，我正在开发一个解决方案，测试38份excel报告是否位于某个位置，并在报告结束时使用特定日期格式化（例如，excel Advazia于2015年9月18日停机），将其作为备份复制到另一个文件夹，在另一个excel工作簿中运行宏（根据日期将报告排序到子文件夹中），最后从原始文件夹中删除38份报告

我更改/删除了其中一个报告中的日期，以便它返回false来测试将发生什么，但它仍在尝试执行IF语句中的代码。但是，如果所有报告的格式都正确，则一切似乎都正常

我很想听到一些关于如何修复错误的反馈，或者是否有更好、更动态的方法来编写代码。谢谢

以下是我目前的代码：

# Declares variable $a as today's date and will add 2 days in "dd MMM yyyy" formatting (Adding 2 days because this will be set up to run on Wednesday and checks for files that have Friday's date)
$a = "{0:dd MMM yyyy}" -f (get-date).AddDays(2)

# Verifies each Excel file is correctly formatted with upcoming Friday's date formatted as "dd MMM yyyy" at end of file. If true, code inside if statement is executed.

这是因为一些值返回true。你应该考虑的是把所有的路径存储在一个数组变量中，然后根据需要一个一个地测试和操作每一个路径。
