I was reading Rebecca's post the other day about file dis-organization and her journey to figure out what to do with a problem that plagues most academics that I know: that of finding interesting articles, downloading them for potential future reading, and then losing track of things (or not knowing where things are).  I have to say that I've struggled with the same problem as well over the past few years and I think I've given up on trying to figure out how to organize things - luckily MacOS has a good enough system search (provided that everything is indexed) that allows me to find (most) things.

My files reside on my hard drive, on MobileMe iDisk (even though that is going away soon), Dropbox, sugarsync, SkyDrive, and ZumoDrive (again, even though this is going away soon). I was thinking of getting Papers for the Mac, but then I thought to myself: what about times when I am not using my mac? In retrospect I should have just gotten it because I almost always use a Mac, and if I don't have one at work I always try to find a way of getting one.  I have tried zotero, but I honestly didn't like it because of the need to use Firefox (which has become pretty unstable over the years, and zotero tends to make it crash, at least in my experience).  Mendeley is not bad, it was introduced to me by @cdetorres, but I've never really gotten "the hang of it" - perhaps it's now time to revisit it, given that it is getting good reviews from people I know and whose opinions I value. The one fly in the ointment is that their iOS client kind of stinks... oh well.

So, my file organization? Just create a folder named "articles" and dump things in there.  If I am working on a specific project, that project gets a folder, but other articles that are interesting just get dumped in "articles" and I figure it out later ;-)
