Why the numbers are so useful (and why you shouldn’t be afraid of them).
Structure
A simple hierarchy
There’s a really simple system behind the numbers that makes it impossible to get lost.
All of your stuff lives inside an ID – your files, notes, and emails.
This page is an ID. Its number is 00.92
. This tells us where it is: in category 00
, which is in area 00-09
. As per the links at the top of this page.
This structure is mirrored on your computer, which makes it really hard to lose stuff.

You don’t have to create these folders. You download the complete structure from this site. (We use a Mac but we also support Windows and Linux.)
Memorable
Read them aloud
These numbers are really handy. Now you can tell anyone where anything is, instantly.
Hey Susan, where’s our backup schedule?
Fourteen-twenty-three!
Think how convenient this is on a video call. No more trying to explain to someone which of your finance folders they need to find.
Or you could stick a number to the side of that piece of machinery that always breaks down. Now everybody knows where to look for the service contract.
Easy
There’s no maths involved
In case it’s not obvious, there’s no maths here. The numbers are just a convenient reference.
So it doesn’t matter if you’re ‘not a numbers person’. There’s nothing to be afraid of.
