I recently got a filing cabinet second hand (I'm on a budget), and it's quite good, four-drawer, does the job.
Then, alas, I read the chapter in the book about filing, and noticed the bit about the metal dividers (follower blocks, I gather they are called).
My cabinet has none, and I can't see any special slots where they might be attached. Is there anything I can do? I could imagine a metal divider could be designed that would just clamp to the sides of the drawer, but I assume that the real McCoy would have a system for slotting in.
I'm hoping someone is going to say: "Yes, you can get follower blocks from blah blah priced blah that fit cabinets that weren't designed to have them"!
