Windows:比较文件夹中的文件并删除不存在的文件 [英] Windows: compare files in folders and delete non existent

问题描述

我在Windows上有巨大的目录+包含文件的子目录. 在Windows命令行上(或通过脚本)，我想比较两个文件夹并从子文件夹中删除不在主文件夹中的文件.

I have huge directories + subdirs containing files on Windows. On the windows command line (or through a script) I'd like to compare two folders and delete files from the subfolder that are not in the main folder.

在下面的示例中，应从子文件夹中删除偶数个文件.

In the example below the even numbered files should be deleted from the subfolder.

folder: C:\folder1
    file1.jpg
    file3.jpg
    file4.jpg
    file7.jpg
    file9.jpg

subfolder: C:\folder1\RAW\
    file1.CR2
    file2.CR2
    file3.CR2
    file4.CR2
    file5.CR2
    file6.CR2
    file7.CR2
    file8.CR2
    file9.CR2

我尝试了在这里找到的几个脚本，但是没有一个可以完成任务.感谢您的帮助！

I have tried several scripts I found here, but non of them do the job. Any help is appreciated!

推荐答案

感谢大家的投入，感谢您的投入，我想出了一个解决方案.在命令行(当然是Windows)上使用它时，效果很好.

Thanks for the input everyone, I came up with a solution also thanks to your input. It works perfect when using it on the command line (Windows of course).

删除之前查看列表:

for %F in ("C:\folder1\RAW\*.CR2") do @if not exist "C:\folder1\%~nF.jpg" echo del "%F"

要删除，请删除"echo"

To delete, remove 'echo'

for %F in ("C:\folder1\RAW\*.CR2") do @if not exist "C:\folder1\%~nF.jpg" del "%F"

希望这对一些人也有用！
