Windows - keep (!) duplicate file names from different folders

Question

All answers I find are about deleting duplicate files, but I want to keep duplicate file names (not files, they only have the same name).

I have been playing around with RAW photo processing software. I have used two different programs to process a set of photo's. After using software A, I made a selection of the images I want to keep (and deleted the others). However, I like the processing from software B better.

So now I have a full set of files in C:\Temp\B\ (980 images), and a selection in C:\Temp\A\ (544 images)

Is there a way to filter out the images I have not selected in A and delete those files from C:\Temp\B\?

I'm using Windows 10, I'm fine with using a bit of scripting in bash (using babun) or Python.

Answer 1

My solution is an adaptation of https://stackoverflow.com/questions/1995373/deleting-all-files-in-a-directory-with-python

I have run this in Visual Studio Code, using the Python extension

import os a = os.listdir("C:/Data/A") b = os.listdir("C:/Data/B") for f in b: if f not in a: print(f) os.remove(os.path.join("C:/Data/B", f))

You can save the following line into a new batch file (.cmd or .bat):

FOR %%A in (C:\Temp\A\*) DO MOVE C:\Temp\B\%%~nxA C:\Temp\X\

Now you have all the files from A, which are present in B, to be moved from B into a new folder X. Do a visual inspection to ensure that everything is OK, and then delete B manually.

You can also run that command from CMD, but you must leave a single percent sign instead of two.

Be very, very careful, as a single missing character can eat all your B files. I ran the command like this first, to make sure that it is safe:

FOR %%A in (C:\Temp\A\*) DO ECHO MOVE C:\Temp\B\%%~nxA C:\Temp\X\
