File Management & Naming (Folders, Versions)
Lesson
3
Why This Lesson Matters
Losing a file feels like losing marks. Most students don’t fail because they can’t write or calculate; they fail because they can’t find the right document at the right time. A clean folder tree, a simple naming rule, and basic version control turn chaos into calm. In Sri Lanka, where you may switch between a phone, a shared PC, and a print shop, tidy files are not a luxury—they’re your insurance. After this lesson, you’ll know exactly where every file lives, what it’s called, and which one is final.
“If you can’t find it in 30 seconds, it’s not organised.”

Step 1: Build One Home—Your Portfolio Tree
Everything you create in this module lives inside one top-level folder: Idasara Digital Portfolio. Think of it as your school bag with labeled sections. Inside it, create these standard subfolders:
Docs – essays, briefs, checklists
Sheets – budgets, tables, charts
Slides – decks, handouts
Assets – scans, images, reference PDFs (add Security subfolder for ID/receipts)
Outputs – final PDFs you share or print
Inbox (To Sort) – temporary landing zone for new downloads
This tree saves time and marks. You never dump everything into “Downloads” again. New files land in Inbox (To Sort); once a day, you move each item to the correct folder. That daily habit (two minutes, no drama) keeps the system clean.
Keep the names exactly as above. When your future self or a teacher opens your drive, they see professional order. It also reduces mistakes at print shops: you open Outputs, click the correct PDF, and you’re done.

The Golden Rule
Name it before you make it. Create the file with a clean name in the right folder, then start writing.
Folder Map — Quick Guide
Put this… | In this folder | Why |
Drafts, essays, checklists | Docs | Styles, comments, PDF export |
Budgets, tables, charts | Sheets | Formulas + charts saved clean |
Presentations | Slides | Slides + presenter notes |
Scans, images, references | Assets (→ Security for sensitive) | Source materials, never shared public |
Final PDFs for sharing/print | Outputs | Fonts/layout locked for any device |
Fresh downloads to sort later | Inbox (To Sort) | Temporary only; zero it daily |
Step 2: Use One Naming Rule Everywhere
Computer search is powerful, but names still matter most. A good name answers three questions at a glance: When was it made? What is it? Which version is it?
Use this pattern for every file:
YYYY-MM-DD_Project-Topic_V1.ext
YYYY-MM-DD sorts your files by date automatically.
Project-Topic is short and human-readable. Use hyphens, not spaces.
V1, V2, V3… show evolution without guessing.
.ext is the file type (docx/gdoc, xlsx/gsheet, pptx/gslide, pdf, jpg).
Examples:
2025-09-06_One-Page-Brief_V1.docx → editable draft
2025-09-10_Mini-Deck_V2.gslides → working slides
2025-09-10_Mini-Deck_V2.pdf → export to Outputs for sharing
2025-09-12_7-Day-Budget_V3.gsheet → updated budget
2025-09-12_7-Day-Budget_V3.pdf → chart PDF for print
“Your future self is the client. Name files your future self can read.”
Bad vs Better — Filenames
Bad | Why it fails | Better |
final.docx | No date; no topic | 2025-09-06_One-Page-Brief_V1.docx |
sliiiides new 2.pptx | Messy, duplicates | 2025-09-10_Mini-Deck_V2.pptx |
Budget.xlsx | Can’t sort or compare | 2025-09-12_7-Day-Budget_V3.xlsx |
scan1234.pdf | Meaningless | 2025-09-08_NIC-Receipt_Scan.pdf |
Brief_latest_REAL.pdf | Panic naming | 2025-09-14_One-Page-Brief_V3.pdf |
Step 3: One Master + Version History (No more “final_final_v3”)
Professionals don’t create ten copies; they keep one master and let the tool track history. Here’s the simple rule:
Keep the editable master in Docs/Sheets/Slides with the current V number.
After big changes or feedback, increase the V number in the filename or use the app’s Version history to name the version (e.g., “Before feedback – 2025-09-10”, “After review – 2025-09-12”).
Export PDFs to Outputs when you need to share or print.
If a mistake happens (someone deletes a paragraph; you overwrite a formula), open Version history, preview the last good state, and restore or copy-paste the lost section back. Test this once now so you don’t panic later.
Add a tiny Change Log at the end of major docs:
Date | What changed | Why |
2025-09-10 | Added chart to page 2 | Visualising category totals |
2025-09-12 | Tightened intro; fixed typos | Teacher feedback |
Two lines save five emails later.
Step 4: The Inbox-to-Zero Habit
Your Inbox (To Sort) folder is a short hallway, not a storage room. New downloads land there. Once per day, move every item out—rename it and file it correctly. This keeps your working folders clean and your mind light. If a file doesn’t belong in your portfolio, delete it. If it’s sensitive (a receipt), move it to Assets/Security. The ritual takes minutes and prevents a hundred small frustrations.
Pair this habit with the calendar block from Lesson 1 (Weekly Device Care) or just after your last study block each day. Consistency beats memory.
Step 5: Find Anything in 30 Seconds (Search like a pro)
Even with perfect names, search helps. Use two tricks:
Date + topic words: type 2025 budget or Brief V2 into your drive search.
Filters: narrow by file type (document/sheet/slide/pdf) and owner (you).
If your drive supports advanced search operators, try:
type: filter by docs/sheets/slides/pdf
title: search in filenames only (less noise)
before/after: limit to a date range
Keep it simple. A good name + one filter beats scrolling.
Step 6: Print-Shop & Shared-PC Protocol
Print shops and lab PCs are helpful if you protect your master files.
Always export a PDF to Outputs and print that. PDFs preserve fonts, Sinhala/Tamil text, and layout.
On shared PCs, use a Guest/Incognito browser, open your cloud, download only the PDF, print, then delete the PDF from Downloads, sign out, and close the window.
Never open your editable master (.docx/.gsheet/.gslide) on public machines unless you must—and if you do, make sure you sign out and clear downloads.
These steps stop accidental edits, font issues, and privacy leaks.
Exercises: Make It Real
Exercise 1 — Build the Tree (10 min) Create the Idasara Digital Portfolio folder with subfolders: Docs / Sheets / Slides / Assets / Outputs / Inbox (To Sort). Take a quick screenshot for your artifact later.
Exercise 2 — Rename Ten (10–15 min) Find ten old files and rename them using the pattern YYYY-MM-DD_Project-Topic_V#.ext. Move each to the correct folder. Delete obvious junk. Empty the recycle bin.
Exercise 3 — Version Drill (10 min) Create 2025-09-06_One-Page-Brief_V1.docx in Docs. Type three lines.
Duplicate a sentence and save as V2 (rename the file or name a version in Version history).
Restore the earlier text using Version history, then re-apply the V2 changes.
Exercise 4 — Output Discipline (5 min) Export the brief to PDF and save in Outputs as 2025-09-06_One-Page-Brief_V2.pdf. Open the PDF on your phone to confirm layout and Sinhala/Tamil text display correctly.
Exercise 5 — Inbox to Zero (5 min) Move today’s downloads into the right folders or delete them. Make Inbox (To Sort) empty. Breathe. That’s what tidy feels like.
Quick Win Rename three files right now using the date–topic–version rule. Future-you will thank present-you.
Artifact to Produce
Create a File Map (Doc) in Docs with:
A screenshot of your Idasara Digital Portfolio folder tree
Five example filenames that follow the rule (one each for Doc, Sheet, Slide, PDF, and an Asset)
A two-line note on how you restored a version during Exercise 3
One sentence explaining when you will use Outputs vs Docs/Sheets/Slides
Export a PDF version of the File Map to Outputs as: 2025-09-06_File-Map_V1.pdf
Self-Verification (SV) Checklist
Portfolio tree created exactly as specified
10 files renamed with YYYY-MM-DD_Project-Topic_V#
Version history tested (restore or copy from older version)
PDF exported to Outputs and opens correctly on phone
Inbox (To Sort) is empty today
Change Log table added to at least one doc
Sensitive items moved to Assets/Security
File Map saved (Doc) and exported (PDF)
Mobile Tip (Android & iOS)
Use your Drive app’s Move and Rename actions (long-press files). In the Files app, check Large files and Downloads first to free space. When saving images from the camera for schoolwork, rename right after capture (many gallery apps let you do this) so the file is searchable later. If your keyboard suggests Sinhala/Tamil names, great—keep the date first for sorting.
Stuck? Fast Fixes
“I can’t see Version history.” Open the file in its native cloud editor (Docs/Sheets/Slides). Desktop-only formats may not show history until converted.
“My names don’t sort as expected.” Use YYYY-MM-DD (four-digit year, two-digit month/day) and hyphens, not slashes or spaces.
“Print shop broke my Sinhala/Tamil text.” Export PDF from your device and print that file; avoid opening the master at the shop.
“Too many duplicates.” Keep one master in the right folder; archive or delete the rest after merging changes.
Common Roadblocks (and Simple Fixes)
If your drive feels messy again, it’s usually because Inbox (To Sort) grew quietly. Zero it at the end of each day. If teammates send you oddly named files, save them into your tree and rename to your standard; never let external chaos infect your system. If you’re rushing to a deadline, fight the urge to dump the final doc in Downloads—export PDF to Outputs and send that; it saves you when you change devices.
“Order is a five-minute habit, not a weekend project.”
Keeping Yourself Motivated
You’ll feel the win immediately: fewer “Where did it go?” moments, faster printing, and no panic at submission time. Note one small victory in your portfolio README—“Restored a lost paragraph via Version history,” or “Printed clean PDF in one try.” The system you’re building isn’t fancy—it’s reliable, and reliability is what teachers and employers value most.
Your First Step Is Complete
You now have one trusted home for your work, a naming rule that travels with you, and a version habit that prevents disasters. Your File Map Doc and PDF are saved, your Outputs folder holds an export that prints perfectly, and your Inbox (To Sort) is empty. This is real digital professionalism.
Next, in Lesson 4: Docs for Writing & Collaboration, you’ll turn blank pages into clear one-page briefs, use headings and styles properly, and practise review comments that make your writing sharper without losing control of your master file.
