What does "round-filed" mean?

[dpkirchner]

Thrown in the (round) trash can. At least that's what I meant. Based on my googling it looks like it's an uncommon term -- way way less common than I thought. Not sure where I first heard/read it.

I think the more common version is “circular file”: https://en.m.wiktionary.org/wiki/circular_file

I've also never heard this term before.
