File folder set up is relatively easy.  I usually make the set-up on my desktop first then zip it and install it where I want it to go on my external Runtime set-up.

First folder: Runtime

Second folder inside of Runtime: Libraries 

If you have textures, then a second folder inside of Runtime: Textures

Click on Libraries and add the following: Character and Pose.  

*Character is where I place the basic character settings: inj/rem files, basic textures for the entire body, main eye, ect.  Pose I use for additional textures if I have them.

Inside both the Character and Pose folder you will want to add whatever your character's name is or label it for ALL of your personal character settings...Example: Dar's Digital Men

Inside the Character and Pose folder you can either keep all your files there, or add one more for each character you make- Example: Mikhail M4  and inside that, all of the inj/rem files and base textures.  

Same for your Textures.

Example of a set up:

Runtime>Libraries>Character>Dar's Digital Men>Mikhail>Inj/Rem files.

Runtime>Libraries>Textures>Dar's Digital Men>Mikhail>Face, Body, Limb, Torso, ect.

Runtime>Libraries>Pose>Dar's Digital Men>Mikhail>Fantasy Skin textures.

When you zip everything you take the Runtime folder with all of your files and compress it.  Once you unzip, you can simply choose your usual Runtime folder and it should unload everything where you need it to be.

Just remember to make your png files (Pictures to go with your Inj/Rem, and all of your set up materials) the exact same name as your pz2's.  

ANOTHER example: Mikhail_Fant_Eye.pz2 (What I label for his fantasy eye materials)

The png will be saved as Mikhail_Fant_Eye.png.

Hope that helps!
