I have two folders. Folder B contains 300 files. The complete set.
Folder A contains a subset of folder B. About 120 files.
I want to delete the files in folder B that exist in folder A
Essentially, folder A is a list of files that are safe to be deleted from Folder B.

If it's any easier, I can simply write the file names to a text file for folder A then delete any files in Folder B if the filename exists in the text file.
Which ever is easier.

How would I do this?

Based on your previous questions I see no reason why you shouldn't be able to figure this out yourself. This could literally be written in one line of code. A simple for command to iterate the files in one directory and use that output with the delete command.

Thanks.
Couldn't figure it out so I've had to code 150 lines in my batch file instead.

This might work obviously Dont forget to change the folder nameS

This might work

Code: Select all

for /f %%a in ('dir C:\FolderA\* /b /s') do (
 for /f %%A in ('dir C:\FolderB\* /b /s') do (
  if exist "%%a" del "%%A"
 )
)

obviously Dont forget to change the folder nameS

%%a will always exist if the working directory is folder A because the first for command created it. You also have to remember that the folder path is not included in the FOR variable when capturing the dir output.
