- Rename files to the convention
Key concepts

The lesson
A naming convention sets the order of elements: date, document type, subject and version, for example 2026-03-14_Memo_Staff-Training_v2.
Writing dates as year-month-day makes files sort in time order. Avoid spaces and special characters that some systems reject.
Publish the convention on one page and apply it to new files from today; rename old files when they are next used.
Step by step
- Draft the naming rules.
- Rename ten sample files.
- Check they sort correctly.
- Publish the convention.
From 'final2' to a file-naming convention
The same office files named two ways — and why the second set can be found and sorted.
Before
Names chosen in the moment: hard to sort, search or trust.
- memo final.docx
- memo final2 (Mary edits).docx
- budget new.xlsx
- Minutes 3rd march.docx
- scan0042.pdf
After
Date, document type, subject and version, in the same order every time.
- 2026-03-14_Memo_Staff-Training_v1.docx
- 2026-03-16_Memo_Staff-Training_v2-approved.docx
- 2026-04-01_Budget_Office-Operations_v1.xlsx
- 2026-03-03_Minutes_Management-Meeting.docx
- 2026-03-05_Letter_Ministry-of-Labour_Received.pdf
What changed and why
- Dates written year-month-day make files sort in time order.
- Document type and subject make files findable by search without opening them.
- Version numbers, with the approved version marked, replace 'final' and 'final2'.
- Hyphens and underscores replace spaces and brackets that some systems reject.
Practice activity
Write the office's file-naming convention.
Expected result: A one-page convention with examples that sort correctly.
