Example command:
wadtools extract --hashtable "%hashfile%" -i "%live%\aatrox.wad.client" -o %desktop%\outbins --filter-type bin

This will result in only .bin files being extracted, but then also every single folder, even in the ASSETS paths will be created with no contents.

The results do vary depending on --pattern or --filter-type with regex for some reason not creating literally every single path, but still plenty unused empty paths, but magic filter does print literally every single directory path.
