Moving from my in-box saga, I am now filing my stuff from my in-box and I have some questions.

I have a two drawer file cabinet and everything fits in the two drawers, a little snugly, but with some wiggle room. I would prefer not to buy another filing cabinet right now (it's about the expense and the space in my office, but also the fear that more space to dump things will be a disincentive to throwing things away). I also have a file holder on top of my desk into which I put my tickler file and a small handful of files that I need to access daily.

I want to know what you all archive and how? I have a really thick folder of product manuals and warranties (yes, I went through it and got rid of everything that pertains to stuff I don't own anymore) that I could archive, but should still be relatively accessible so that I will put new stuff in there as it comes in. What do you do in cases like this?

I have all my tax stuff from previous years archived in a miracle box. Is this a good way to deal with my "product" file? What else do you all archive? How do you archive? Do you have a system for tracking what is there? How do you keep it accessible? And one more thing, what papers should I put in a safety deposit box?
