Organizing Your Computer: The Classification Plan That Works

The desk cluttered with files, the « New Folder (2) », documents named « scan.pdf » and « truc_final_v3_VRAIFINAL.docx », downloads in a common grave : digital disorder is costly — time (daily minutes spent searching), stress, and sometimes lost documents at the worst moment. The remedy isn’t heroic discipline : it’s a PLAN — a simple hierarchy, naming rules, and three habits that make it stick. Here’s the complete system, installable in an afternoon, designed to survive real life.

The plan: a hierarchy that thinks like you

The founding principle : few root folders, obvious names, never more than three levels deep (beyond that, you don’t go down — search does the rest). The proven plan for an individual, to adapt : 01-Administrative (subfolders by domain : Taxes, Bank, Housing, Health, Vehicle, Work, Family — the heart of the system, the one that helps at the worst moment) ; 02-Projects (one folder per ongoing project : Kitchen-Renovation, Trip-Italy, Association — everything that has a beginning and an end) ; 03-Personal (CV and applications, writings, tracked hobbies) ; 04-Archives (closed years and finished projects — you move things there, you don’t work there) ; and photos live elsewhere — in the photo library, which is their real system (albums and dates — our photo guides : don’t duplicate in folders) ; and music/videos in their apps. The numbers before the names force the display order — administrative always comes first. This plan lives in ONE place : your synchronized space (iCloud Drive, Drive… — our File guides) : synchronized = backed up + accessible from your phone : a classification that only works on one device is half a classification.

Naming: the rule that makes everything retrievable

Naming is half the system — ONE rule, applied everywhere : YYYY-MM_What_Who.extension — the date first (year-month : chronological sorting becomes automatic), the content next, the party involved if useful : « 2026-03_Boiler-Invoice_Dupont.pdf », « 2026-07_Rental-Contract_Nice.pdf » — compare to « scan(3).pdf » : the first one is found by sorting, searching, AND simple reading ; words separated by hyphens or underscores (no accents or exotic spaces for maximum compatibility — a comfort habit, not an obligation) ; versions in a clear suffix when needed (« _v1 », « _v2 », « _final » — and the real final is the one in PDF) : but the best version management is that of online documents (built-in history — a single copy that keeps its memory) ; and renaming upon arrival — the cardinal reflex : every incoming file (scan, download, attachment) is renamed and filed AT THE MOMENT it arrives — thirty seconds hot vs. ten minutes of searching later (the phone scan is renamed at digitization — our scan guides). For existing files, no retroactive panic : the stock is handled separately (see below) — the rule applies first to the flow.

The right reflex. Create the folder « 00-Sorting-Box » at the top of the hierarchy : EVERYTHING that arrives without an obvious destination lands there (instead of the Desktop or Downloads) — and the five-minute weekly ritual empties it : rename, file, delete. It’s the pressure valve that makes the system sustainable : no one classifies perfectly on the spot every day — but everyone can empty a small box on Sunday. A system without a pressure valve breaks ; this one bends and holds. (And the Desktop becomes what it should be : empty.)

The big cleanup: handling years of mess

The historical stock is handled strategically, not heroically : 1) Create the new plan (the hierarchy above, empty) : new first, old later — starting today, the incoming flow is clean ; 2) Make a folder « ZZ-Pre-Sorting » and move EVERYTHING in bulk there (Desktop, Downloads, historical Documents) : the psychological effect is immediate — clean space, nothing lost ; 3) Retrieve by need AND in batches — the two-path rule : every file you go to SEARCH in ZZ is filed on the way (sorting by use — useful files naturally migrate in a few months), plus a 15-minute batch per week on obvious categories (type-based search helps : all bank PDFs are found by keyword and filed in bulk) ; 4) After six months to a year, what’s still sleeping in ZZ was useless : archive the folder as-is in 04-Archives (the safety net : nothing is deleted) and forget about it. This method avoids the classic trap — the heroic sorting Saturday abandoned at 4 PM that leaves a worse mess than before : here, the system works from day 1, and the past dissolves instead of being fought. Finally, duplicates (the same document in four copies) : duplicate-finding tools help, but the real answer is the plan — one document, ONE place, and synchronization that shows it everywhere.

What complements the plan: search, shortcuts, hub

Modern organization relies on three allies : search — Spotlight and equivalents search INSIDE documents (the OCR’d PDF is found by its content — our scan guides) : the plan is for STORING peacefully, search is for finding fast — both together forgive classification imperfections (hence the importance of rich naming : every word in the name is a hook) ; shortcuts and favorites — the three current folders (the active project, the current administrative year) pinned in the sidebar : one-click access to 90 % of uses, without navigating ; tags for cross-cutting items (the same document « Taxes » AND « Renovation » : it lives in Taxes, the Renovation tag makes it appear there too — in moderation : three-four useful tags beat thirty decorative ones) ; and family sharing — the household’s Administrative folder shared between spouses (each one files, each one finds — the end of « did you have the contract ? » : our family organization guides), and the plan EXPLAINED to concerned relatives — the best system in the world doesn’t survive a household that files elsewhere. Final step : transmission — a clear plan is also what will allow a relative to find their way when needed (our digital succession guides) : organization is a deferred kindness.

Frequent questions

Should you also classify your emails ?

With the same streamlined philosophy : a few broad folders (or labels), mass archiving rather than fine sorting (email search is excellent), and above all — important attachments EXPORTED to the classification plan (the contract received by email lives in 01-Administrative, not buried in a 2023 thread : the inbox is not a safe — our guides for a saturated inbox).

Would a document management software do better ?

For an individual or a freelancer : the trio of synchronized folders + naming + search does everything, for free and without dependency (your files remain files — readable in twenty years, transferable everywhere). Specialized tools are justified in companies (validation workflows, fine-grained rights). Beware of « magical » apps that lock your documents in their format : longevity is the first criterion of organization.

And work files mixed with personal ones ?

Separate at the root (a Pro space, a Personal space — ideally two distinct accounts/spaces : the employer’s shouldn’t host your taxes, and vice versa) : the boundary protects both worlds (confidentiality, job departure, backups). The internal plan of each space can be identical — it’s even recommended : one mental gymnastics.

What to remember

Digital disorder isn’t a personality trait — it’s the lack of a plan : four numbered root folders (Administrative, Projects, Personal, Archives) in the synchronized space, the YYYY-MM_What_Who naming rule applied to incoming files, the 00 sorting box emptied five minutes per week, and the historical stock dissolved gently (ZZ-Pre-Sorting, retrieval by use, archiving of the rest). Search and favorites provide speed, family sharing provides robustness, sobriety provides longevity — neither over-classification nor all-search. One afternoon of installation, five minutes of weekly maintenance : every document in the household within thirty seconds’ reach, even on the emergency day when it really counts. « New Folder (2) » has lived long enough — its successor has a name, a date, and a place.
