Johnny.Decimal is a system to organise your digital life. It’s designed to help you find things quickly, with more confidence, and less stress. In real life, if you stored your stuff in piles of badly-labelled boxes you’d never find anything again. If you put those boxes in boxes, in boxes, you’d never know which box to open to find the next box. It would be chaos. But I just described how you save your computer files.

Imagine your computer as a physical storage space. We can’t put everything on the floor, so we buy some shelves. If we had a limitless number of shelves, we wouldn’t know which one to look on when we wanted to find something. So we get ten shelves. We decide to dedicate each shelf to an area of our life.
