How to delete a file from multiple zip archives using 7-Zip

Question

I have a thousand zip archives that all contain a file I want to remove. I can get 7Zip to remove them one file at a time from the command line:

7z d -r archive.zip *.pdf

but how would I apply that across all the files, which are themselves grouped in sub-directories?

Answer 1

Try this:

for /r %v in (*.zip) do 7z d -r "%v" *.pdf

But no idea if it's working, just wrote out of my head :P

Answer 2

FOR /F "tokens=*" %%G IN ('dir /b *.zip') DO 7z.exe d -r %%G *.pdf

This works almost in the same way as the accepted answer. Only the way how the files are gathered is different. Whereas the answer above uses for /r to run through all directories and subdirectories, this one parses the output of the command dir /b *.zip to get all the files relevant.
The 7zip command remains the same and only the parameters are changed.

Note: To run this outside of a batchfile replace %%G with %G

Answer 3
