Okay, to you this might seem dumb, but to me this is a fantastic way to set out a folder. My Download folder is set out like this.. I have separate folders saying where i got the downloads from, say Simply Styling for example, the folder will say Simply Styling, then inside that folder, there will be other folders saying Clothes, Bedroom, Floors etc etc. Same with the others, such as Mod The Sims 2, i will abbreviate the folder calling it MTS2 and do the same routine as the Simply Styling folder, and my CEP will have it's own folder saying "CEP" with all the CEP stuff put inside the CEP folder. Say if you have downloaded a clutter from Simply Styling, then make a folder with in Simply Styling calling "Clutter" then make folders in the Clutter folder, so if you have downloaded a kitchen clutter, make a "Kitchen" folder inside the Clutter folder and place your kitchen clutter download inside that. Having a neatly organized Download Folder makes things so much easier. Also, to give a bit more help, Here's Collection Icons link
