Lesson Notes

Read through the key concepts before you try the challenge.

Organization is a decision made once

On the job

You inherit the shared drive at Lakeside Medical Associates.

It contains 1,400 files across four levels of folders. Names include 'letter final.docx', 'letter final v2.docx', 'letter FINAL USE THIS.docx', and 'Copy of Copy of intake form.docx'. Nobody can find anything, so people save new copies rather than search — which makes it worse every week.

Your task: Design a structure and naming convention that stays usable as it grows.

Folder structure should mirror how people look for things, not how they were created. Most offices organize by function, then by year, then by type — because that is the order someone actually thinks in when searching: what kind of thing, from when.

Naming matters as much as structure, because search only works if names are predictable. A good file name contains the date in year-month-day order, a description, and a version if versions matter.

PoorBetterWhy
letter final v2.docx2026-09-01_Insurance-Appeal_Ramirez_v2.docxSorts by date, says what it is, versions unambiguous
Copy of intake form.docxIntake-Form_Template_v3.docxNames the purpose rather than its history
notes 9-1-26.docx2026-09-01_Staff-Meeting-Notes.docxYear-first dates sort chronologically in any file list
FINAL FINAL.pdf2026-08-15_Policy-Manual_v4-approved.pdf'Final' is not a version; a number and a status is
Naming that works against naming that does not
Year-first dates — 2026-09-01 rather than 09-01-2026 — are the single highest-value naming habit. They sort chronologically in every file list automatically, with no effort and no special tooling. Once you have used them for a month, the alternative starts to look broken.
Check your understanding

Why should dates in file names be written as 2026-09-01 rather than 09-01-2026?

Challenge

Apply what you've learned in this lesson.

Fix a real mess, at small scale.

  1. Design a folder structure for a small medical office covering administration, clinical forms, billing, and templates. Go no deeper than four levels.
  2. Write a one-page naming convention someone could follow without asking questions. Include at least three worked examples.
  3. Take a real folder on your own computer holding at least twenty files and reorganize it to your structure, renaming every file to your convention.
  4. Write three sentences on what made the reorganization hardest, and what rule would have prevented it.
