删除批处理文件中具有特定扩展名的文件 [英] Delete file with specific extension in batch file

问题描述

我想在批处理文件中递归删除所有具有特定扩展名的文件.

I would like to recursively delete all files with a specific extension in a batch file.

我知道以下命令:

del /s *.ext

但是，这在Windows上也会删除具有其他扩展名(例如)的文件..ext1或.ext2.造成这种情况的原因似乎是该文件的8.3文件名以.ext结尾，因此扩展名较长的文件也将匹配.

However, this does on Windows also delete files with other extensions like e.g. .ext1 or .ext2 . The reason for this seems to be that the 8.3 file name of such a file ends with .ext and therefore also the files with longer extensions are matched.

我正在寻找上述命令的替代品，该命令以递归方式删除所有扩展名为.ext的文件，但保留扩展名更长的文件.

I am looking for a replacement to the command above that recursively deletes all files with .ext extension but keeps files with longer extensions.

推荐答案

where 命令的工作方式略有不同(关于通配符和短名称).放置一个 for/f 循环，就完成了.您的示例将转换为:

the where command works a bit differently (in regards to wildcards and short-names). Put a for /f loop around, and you're done. Your example would then translate to:

for /f "delims=" %%a in ('where /r . *.ext') do ECHO del "%%a"

注意:我通过回显命令解除了 del 命令的武装.在确定问题确实符合您的要求之后，请在故障排除后删除 ECHO .

Note: I disarmed the del command by just echoing it. Remove the ECHO after troubleshooting, when you are sure it does exactly what you want.
