Hmmm, mine's only just over 3GB so 30GB does seemlike a lot to me! It's not the size in MB or GB though, it's the number of folders as Logan says. I'm not sure that the list doesn't start shrinking in width even before you hit 255 but that seems a likely culprit since 256 (0-255) is the largest number you can represent in one byte. Another reason to split out some of those folders is that pre P5, you have can't use more than one level of subdirectories so all that nice multi-level stuff doesn't work and you have one long list which is tedious to scroll through. I'll give my fellow coders the benefit of the doubt and not necessarily call it a bug. Bill Gates supposedly once said that no one would ever need more than 640K of memory. Poser had and still has a lot of old code in it. I'm sure that back then, no one imagined that there would ever be a need for 255+ pose folders. MAT and MOR posed hadn't even been invented and 30GB would have probably held the runtimes of every Poser user in the world. You can also rename and move pz2 files to the hand (hd2) and face (fc2) folders. I think cameras is probably used most because usually people have fewer items there.
