I use ACDsee to organize all my digi supplies. I have for years.
The nice thing is you just tag them, so you aren't actually moving your files. You can have endless amounts of categories.
Here's a little video I created on how I tag my supplies and my photos. I will not scrap without ACDsee. Honestly, I can't tell you how much time it saves me. I've been doing digi 15 years this summer and I think I've been using a version of ACDsee probably 12 of those years.

I think it's a must have program.
