How do you organize your papers? Possible Duplicate:
  Do you use any article organizers?   




[[ This is intended as a wiki question ]]

I have tons of papers on the subject I'm studying.  When you get them from ACM or someone's website, they're usually called something like kautz-a1.pdf or, my favorite, paper.pdf.  What I've done is organize them by:

year - first author's last name - paper title.pdf


So for example, in /papers:

2007 - Wang - PRT for RT indirect lighting using spectral mesh basis.pdf


This seems to work, and I can usually find what I'm looking for.  I mirrored this folder on DropBox, so I can pull down the collection if I happen to be working on another computer than my main.

How do other people store them?
I use Mendeley, which allows you to tag your papers, find them by topic, author, export bibtex files, and so on.
