Once I had my basic runtimes set up, I took time to sort them further with many many sub folders so I could find their contents easier. For my V3 Clothing Runtime, I sorted the character and pose folder further by adding sub folders called: Morphing clothing, non morphing clothing, jewelery, shoes. This way when I'm wanting to use something morphing, I go to the morphing clothing folder. I know to look for textures for that outfit in the pose folder in the "morphing clothing" folder. Makes like easier. I also took it even further (yes I'm anal when it comes to organizing). Inside the Pose folder and each of the "morphing clothing" and "Non morphing" folders, I sorted further by outfit name. This way anything related to the MFD is found inside the MFD. Anything for the Mediteranean Wrap Dress is found in a folder for the Mediterannean Wrap Dress. I did that same thing for my hair file textures in their runtime. Once you have the basic runtime set up, you can organize the contents of the library folder anyway you like.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
