I only have 4 files - two that are flat, one that is half round, and a rat-tail

and I can easily put all four ontop of my computers (my big floor case PC or on my notebook)

I think my wife has a couple nail-files around

but from the size of my PC case, I would guess I can get maybe 15 or 20 files on my computer.

Ive seen photos of old mainframes that would fill up a small room. Ill bet you could put hundreds of files on those things, maybe thousands!

but to be honest, Im not sure why you would want to - Mine tend to get metal dust on them, and I keep my files in my toolbox in the garage

not on my PC.
