@SteveSawczyn I stick labels on them. And so far I've had no ruination that I know about. I suppose one could just not zip them shut before putting them in the file folders as I do that way they'd still be contained but also get air. What do I know.
@robini71 It probably works perfectly fine. I'm an over-worrier so tend to worry about things that likely will never go wrong. Ultimately, you have a system that is working, I have stacks of stuff that I'm sure I'll file eventually but which will remain a disorganized mess until I do. :(
@SteveSawczyn I worry too so I empathize. It's why I never a truly air tight safe because I read about them having mildew issues bleh.
@robini71 I had an airtight safe and that's exacly what happened.
