As far as keeping everything organized, this is what I do and so far it has kept me from going insane, cross-eyed, postal, etc. I noticed really really early how the Runtime folder can get out of control just like weeds in a garden. I went into my runtime folder, selected lets say the library open that up and say I go to "pose" I've consolidated all my poses into a folder labled "poses" inside that I've split them up into Female--Male--Creature poses. Back in the main pose folder I've made a folder named Clothing and one for Hair, one for buildings. Inside those folders I've broken them down accordingly. I'm a fan of DM items so I have a folder strictly for them "DM Buildings...DM Characters". I have a folder strictly for 3DCelebrity figures but its in my "Characters" folder in the Pose main group...so when I've loaded my Figure I'll go to my Pose and if it's a hair or product I'm looking for, I go straight to my hair and then everything related to all hair products I have is in that folder I'll only have to search thru Hair items instead of A-Z. Also the trick is to keep it up, the more you buy the more "weeds" you get and then it's almost like a nightmare if you slack off. Another thing I found helpful is when you backup your Poser downloads I've placed everything in their proper groups, like a disc for characters, clothing, hair etc. After I've downloaded items I've bought or worse yet all those lovely freebies out there [aka the fast growing kind of weeds]I've made folders up and moved my downloads into them based on what they are, "Clothing" "Hair" etc. I've "lost" items that I swear I've loaded but could not find and being able to go straight to the disc that has like just "Characters" has saved me from surfing through 30 plus discs looking for that 1 character texture. Dunno, that's what I do, kind of seems nit-picky but I can't operate properly in Poser when it has been a while since I consolidated my files....As far as knowing where the file exsists hehe when you're become a Poser addict...you'll know what to look for and I've found my method above has saved me precious time. But everyone has their own ways of keeping up with their inventory, so you might come up with something different. That's my 2 kb's worth..
