Evening all

I recently acquired a rather nice old filing cabinet. Looks vaguely military but it's nice and deep, has exceptionally robust runners and 4 drawers not 3 so it should actually allow me to finally consolidate all of my exciting (!) assortment of storage places.

HOWEVER...

it's very narrow. I can get A4 sheets in it but I've measured and the drawers are actually 307mm wide (which I suspect was originally designed as being 12 inches) and I can't find folders anywhere to fit it. Can anyone help?

If it comes to it, I'll have to just buy normal foolscap and guillotine them, but it seems like a bit of an effort so I thought I'd ask the experts first!

Many thanks in advance
