One of the biggest problems with Poser, is finding your bloody items in its stupid Library system, ugh! ;) While Poser 7 help with this problem, there is a huge need to sort the entire folder system out so you can find individual things, easily.

Poser gets in such a mess, because ALL your files get stuck into the same Runtime, so all your Vicky, Mike etc stuff gets lumped into one ugly, huge folder...which would be atrocious and not acceptable in any other system nowadays.

Alas, Poser is built on an old system, and trying to keep it all compatible, has meant the file system is antiquated and ends up totally bloated, an un-navigable mess after a while. So, what you need to do, is make multiple folders, in which to store and install things, in a logical manner.

As you can see in the pics above, I made a lot of folders, neatly named on my hard drive, so I can find and seperate Poser content precisely. Also, what I do is store all downloaded files into the appropriate folders with web pages and pictures from DAZ3D etc, so I have info on each file.
So for Mike 3 for example, I mave a folder inside it named "Mike3 DAZ3D Armour" with the downloaded file and a copy of the Web page about the item.

This makes things much easier when you are hunting for an item of a specific look, or for info.
Install or unzip Poser content inside these folders, NOT in the Poser program install area itself.

Another thing to perhaps do, is copy copy your Poser.exe file into each folder, as some old Poser installers look for the "Poser.exe" file in that specific directory, or they won't install.
