How to delete N files of X type from Y subfolders from a Windows batch file?
提问by Jeremiah
I'm trying to write a windows batch file that can delete files from subdirectories. I would rather not hard code the directory structure in, so I can use this process with other projects.
我正在尝试编写一个可以从子目录中删除文件的 Windows 批处理文件。我宁愿不对目录结构进行硬编码，这样我就可以将此过程用于其他项目。
- I need to delete files of X type,
- I have the parent folder
C:\MyProject, - There are Y subfolders
C:\MyProject\?, - There are N files to delete.
- 我需要删除X类型的文件，
- 我有父文件夹
C:\MyProject， - 有 Y 个子文件夹
C:\MyProject\?， - 有 N 个文件要删除。
Is there a quick del(of type) function I am simply missing?
是否有del我只是缺少的快速（类型）功能？

Actually you can use the standard del command:
实际上你可以使用标准的 del 命令：
c:
cd MyProject
del /S *.type
Where type is the extension you want to delete and the /S parameter will check in all subfolders of MyProject.
其中 type 是您要删除的扩展名，/S 参数将检查 MyProject 的所有子文件夹。

If the del command didn't have the /S flag to delete recursively, I'd use AWK to do something like this (you'd need the UNIX tools for Windows):
如果 del 命令没有 /S 标志来递归删除，我会使用 AWK 来做这样的事情（你需要适用于 Windows 的 UNIX 工具）：
dir MyProject\*.* /ad /s /b | gawk "{print \"del \\"\" ##代码## \"\*.type\\"\";}" | cmd
My 2 cents, in case you ever need to do something similar (applying a program to all files of X type in all subfolders) with a command that lacks a recursive flag.
我的 2 美分，以防您需要使用缺少递归标志的命令执行类似操作（将程序应用于所有子文件夹中的所有 X 类型文件）。
