Well I'll tell y'all, not one of us files properly! Back in 1973 more or less I went to a vo-tech and one of the first things taught in machine shop was how to file. I don't remember details but for starters a file never touched metal without chalk on it. Wonder how much file chalk is sold these days? Secondly a file was cleaned after every stroke and rechalked if necessary. It never touched metal other than the metal it was cutting. Needless to say, you put pressure on the teeth only in the direction of the cut and lifted completely off of the material during the reverse motion. A lot more about angles and pressure and such but I've slept a lot of times since then!
I do have files in good shape I have used over ten years, and I have files I wear out fairly quickly. I can file to a tiny fraction of a thousandth of an inch and I can sharpen chains and butcher knives with a file. Criminal to some butcher knives, perfect for the Old Hickory high carbon black iron blades that are used and abused. Old Hickory knives are perfect for work knives and I have worn out over a dozen boning knives. Still have a few laying around for shop knives. When you use them cutting things that require you sharpening every ten or fifteen minutes in the field there is no time for niceties and a file is the sharpener of choice.
We all abuse files according to "best practices", most knowing full well we could treat them better. I clean my saw file after every tooth and lift completely off on the backstroke. If I take more than a few strokes on a tooth I will clean mid-tooth. Chalk, a light oil, or graphite would no doubt prolong the life of my saw files. Somewhere speed and convenience meets up with file life and cost. That can be a little different spot for all of us!

How do you clean your saw files, same way as a flat file (file card thingy)? You think kids sidewalk chalk would work? I have tons of them lol
