PURPOSE Clear file names make documents easier to search, sort, and understand. GOOD FILE NAMES INCLUDE Topic, date, version, owner or department when useful, and document type. EXAMPLE Use '2026-05-budget-review-v2.xlsx' instead of 'final_new_reallyfinal.xlsx.' AVOID Avoid vague names, special characters that may break systems, and version names that lie to everyone. BEST PRACTICE Use dates in YYYY-MM-DD format when chronological sorting matters.
