Hi, i don't know if you've already look at the software "space monger" but his display is very great because in the same time you have an idea about what files take the most space in your partition/folder and very easy to reorganise your datas, so if you don't know this software just look at this screenshot:

Sorry to give you this link from another software, i apologize in advance, but it's the only way to show you what look like the display, i imagine this display in dopus and better if it's a dual lister.....pffff! it would be great !
Thx
YOYO
