如何使用Windows批处理文件删除不包含某些字符的文件？

Question

How can I delete files that do not end with the pattern .PDF_*.pdf ? 如何删除不以模式.PDF_*.pdf结尾的文件？

AA00A6E2.PDF
AA00A6E3.PDF
AA00A6E3.PDF_01.pdf
AA00A6E3.PDF_02.pdf
AA00A6E3.PDF_03.pdf

I have been trying all sorts of variations around the following syntax: 我一直在尝试围绕以下语法的各种变体：

FOR %%F IN (%varFolderSource%\*.*) DO IF NOT "%%~xF" == "*_*" DEL /F /S "%%F"

But I can't seem to crack it. 但我似乎无法破解它。

%varFolderSource% is a folder path: C:\Temp etc.

I am running this in a Windows 7 batch file. 我在Windows 7批处理文件中运行它。

For /f "delims=" %A in ('dir /b /a-d ^|findstr /i /v /e /r "\.PDF_[a-z0-9]*\.pdf"') do echo %A

Type 类型

for /?
findstr /?

In a batch file use %%A rather than %A at command prompt. 在批处理文件中，在命令提示符下使用%%A而不是%A 。
