export all function

How can I export all the files from a specific section of the WAD? I tried to do this with the sprites section (Ctrl+A, then entry/ save as...) and it worked- however repeating the process with patches or sounds doesn't work (it only works with one file at a time, which is time-consuming).

The process you've described will work no matter what section you are in. I've just tried this quickly to be sure, works fine for sprites, patches, sounds, etc.

Try it again. Make sure you click on a lump in the list (so that the focus is on the list) before pressing CTRL+A. If it doesn't work, let me know exactly what step is giving you a problem.
