Question

Is there a way to save in a text file all the folders (full path) that don’t contain a file named “test”, for example.

Answer 1

This should work

@echo off
for /d /r %%f in (*) do (
if not exist %%f\test.txt (
echo %%f >>C:\folders.txt
)
)

That will output all folders that don’t contain the file test.txt to the file C:\folders.txt, just tweak/adjust to your needs.
