I had it given to me by the company (I owned my own site at the time, they gave me a copy in exchange for banner advertising on my site), and actually sat down and organized it all, but then I slacked off. I lost it though when I had to restore my computer (and the email with the serial code was lost as well), so I purchased it right away - I totally don't regret it, even though I don't use it for organizing. I actually prefer to browse my files in ACDSee more than through Windows (the plus for me is that I can preview PSD files, which Windows isn't capable of doing).
If I wasn't so lazy and didn't have SO much stuff, I'd start organizing again...because I did use it that way when it was categorized. LOL!
