atiyatia: Rwills has some great suggestions.

It may take awhile (it took me a few days because I have thousands of downloads) but it is worth it in the long run to go ahead and do the subfolder organization:
http://nene.modthesims2.com/wiki.php?title=Game_Help:Organizing_Custom_ContentThe link above is a life saver. A few days organizing once and sacrificing game play is better than having to go through every single download to find one culprit all the time because after this, you know where everything is. Because of this, I can go through them by groups. I usually start with removing my Hacks / Mods (because they are usually the culprit). But this way, I can go through them by groups, too (
Ex: Hacks / Mods: Careers, then Hacks / Mods: Items, etc.). At least they are all in one place as opposed to going through thousands of downloads to try to weed out all my Hacks and Mods individually. This is just way too time consuming and you are more susceptible to headaches / destroying your computer this way. Plus, not all Hacks / Mods are easy to find.

faiithx: Use the organizing custom content link above (the second one). Downloading hint: When I download, I download more than one or two CC items at a time. Usually, I'll do like 9 or 10 items. So, what I do, is
NOT download them into their sub-folders right away, but I make a new folder with either the date, or labeled "new downloads" so I immediately know where the culprit is if my game won't start.
Hope that's helpful for you guys.
