How to find a folder in which there is no specific file

[salazor]

I have files .zip and auxiliary descr.wd3 in folders - unfortunately, .zip files have 3564 and descr.wd3 3533 how to find folders in which there are no files descr.wd3

[void]

To find folders that contain a zip file and do not contain a descr.wd3 file, search for:
child:.zip !child:descr.wd3
