I sort my downloaded files by vendor and then by product number.

So for example, I'm a huge fan of Renapd and have a number of her items. I have a folder with her name on it, and inside I sort the files I have by their 5 digit product number found in the address.

I'm rather sorry I didn't take a different route to sorting though. In hindsight I think sorting by figure and then by theme would have been better.

Have all of V3 items in one folder, subsequently sorted by "shoes", "dresses" etc.  And then if there were any texture addons for something, they could go into the folder that contained the original outfit.   As it stands now, I have the original outfit (IE: Daz) in one folder, and then the addon textures for the outfit in a number of different folders based on the vendor who created the texture. Makes finding things to install a bit difficult.

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
