删除文件夹B中与文件夹A批处理文件中的文件具有相同前缀的文件

Question

I want to do the following. If I have folder A:

File1.ext
File2.ext
File3.ext

I want to delete anything in folder B that begins with the same prefix. So if I have this in folder B:

File1-1.ext
File2-3.ext

I want them to be deleted.

I've been trying to use this:

For %%F In ("C:\FolderA\*.*") Do If Exist "C:\FolderB\%%~nF" Del "C:\FolderB\%%~nF"

But it won't work for me if there is a "-1" for instance on the file in folder B. I tried using an asterisk but that did not work. I'm totally brand new to this, and your help is appreciated. Thanks!

Answer 1

What you have to do is to take the filename ONLY from files in FolderA and search if exist in FolderB . So, you need to try something like this:

for %%I IN ("C:\FolderA\*.*") do del /q "C:\FolderB\%%~nI*"

where %%~nI means filename only of files found in FolderA .

Hope this helps!
