HOW SINGAPORE EDUCATION WORKS · Adult and later-life digital learning
Find your next learning step
Inventory course files, separate learning evidence from replaceable downloads, verify any cloud copy, then change local availability or delete only with a tested recovery path.

Finishing an online course often leaves slides, videos, duplicate PDFs, assignment drafts and synchronised folders across several devices. The safest cleanup is not “delete the largest files”. It is a retention decision: what evidence must remain, what can be retrieved again, what contains personal or licensed material, and what recovery method has actually been tested?
This is a personal learning workflow, not legal, employment, records-management or institutional policy. Course providers, employers and public agencies may set retention, confidentiality, copyright and account-expiry requirements. Follow those requirements before applying any suggestion here.
The choices at a glance
| What you notice | Likely issue | Useful next move |
|---|---|---|
| The device is full but cloud icons are visible | Local copies may be consuming space | Verify sync, then use the platform’s make-online-only or free-space control |
| A folder has many versions named final | Evidence and drafts are mixed | Choose a verified final plus required process evidence; archive or remove duplicates deliberately |
| A course account will close soon | Replaceable material may become unavailable | Check permitted download/export rights and preserve required evidence before expiry |

Repair and practise
Recall, transfer and questions
A file can be valuable because it proves completion, records feedback, supports later practice or cannot be retrieved again. Size is only one attribute. A tiny feedback note may matter more than a large replaceable lecture video.
Separate three questions: Must I retain it? May I retain it? Can I recover it? A provider’s licence may forbid redistribution even when a download remains on your device. Personal data may require secure handling rather than indefinite storage.
Cloud sync is not automatically an independent backup. A deletion in a synchronised folder can propagate across devices. Confirm the service’s actual status and recovery options before changing anything.
| Class | Examples | Default question |
|---|---|---|
| Required evidence | Certificate, assessed submission, official feedback | What rule or future need requires retention? |
| Reusable learning asset | Own notes, permitted template, worked example | Can I find and understand it six months later? |
| Replaceable download | Provider PDF or video still available under licence | Is retrieval dependable and permitted? |
| Sensitive or restricted | Personal data, workplace case, licensed dataset | What authorised location and deletion rule apply? |
| Duplicate or temporary | Partial download, cache, repeated export | Can I verify another complete copy before removal? |
Name the retention reason in a short inventory. “Keep because assessed feedback supports portfolio claim” is testable; “might need” is not. Add an owner and review date for shared or work-related material.
Do not move institutional or employer files into a personal cloud account merely to save space. Use authorised storage and transfer routes.
Assumptions: Mei’s fictional folder contains 8 GB of provider videos, 2 GB of duplicate slide decks, 1 GB of project files, 700 MB of her own notes and 300 MB of certificate, rubric and feedback. The folder is synchronised to an approved OneDrive account; the provider says video access continues for one year, while her learner account closes in 30 days.
Mei confirms the sync client shows completion, opens three files from the web interface, and exports the permitted certificate and feedback. She keeps the 2 GB of project evidence and notes locally plus in the approved cloud, retains the required 300 MB records, removes verified duplicate slide decks, and uses Free up space for the 8 GB video folder rather than Delete.
Checked result under these assumptions: local use falls from 12 GB to about 3 GB: 12 − 2 duplicate − 7 video local copies = 3 GB. The online-only videos remain listed but require internet access; Mei tests one after the change. The calculation does not promise that every platform reports placeholder size identically.
If provider access or licence terms differ, the decision changes. The example demonstrates the questions and verification, not a universal retention period.
Check the path first. Is the folder local only, synchronised, a shortcut to shared content or an offline cache? A familiar folder icon can hide different behaviour.
Check ownership next. Files supplied by a provider may be licensed for personal study, not transfer. Collaborative work may belong in a team repository. Certificates and submissions may contain identifiers that should not be copied casually.
Check expiry last: course access, institutional accounts, recycle bins and version histories may all have limits. Record the date and source rather than relying on memory or assuming a vendor’s current default applies to every account.
- Pause active downloads and wait for synchronisation to complete.
- Create an inventory of location, size, owner, sensitivity and retention reason.
- Open a sample from the destination or web interface to verify readability.
- For synchronised material, prefer a platform’s online-only or free-space action when the goal is local capacity.
- Delete verified duplicates in small batches and inspect the service’s recycle or recovery view.
- Record what changed and schedule a later review of the retained archive.
The distinction between Free up space and Delete matters. Microsoft states that making a OneDrive file online-only removes the local copy without deleting it from OneDrive; deleting a synchronised file deletes it across OneDrive locations.
Never test deletion on the only copy of irreplaceable evidence. Use a non-sensitive sample and verify recovery before relying on it.
Guided pass
- Choose one small course folder.
- Classify five representative files together.
- Verify one cloud item without deleting anything.
Shared pass
- Learner proposes keep, archive or delete for each class.
- A partner challenges the recovery assumption.
- Learner revises the plan and tests an online-only sample.
Independent pass
The learner completes a dated inventory, performs one reversible batch, calculates space reclaimed and confirms that required evidence still opens from its intended location.
After one week, retrieve one archived note, one assessed file and one online-only resource. Record whether the filename, folder and access instructions were sufficient. A successful cleanup remains usable after the memory of the course fades.
Changed-context transfer: compare a personal hobby course with employer-funded training. The file types may look similar, but ownership, confidentiality and retention authority can differ. Re-run the classification instead of copying the earlier decision.
Adult learners move among national skills programmes, universities, employers and global platforms. Interface labels vary, but the durable sequence is inventory → authority → verification → reversible change → recovery check.
Is a green sync tick proof of backup?
It is evidence of a status reported by that client, not proof of an independent backup. Open a sample from the intended destination and understand how deletions propagate.
Should I keep every certificate forever?
Follow applicable rules and likely evidence needs. Keep an authentic, readable copy with provenance; avoid unnecessary duplicates containing personal data.
Can I keep downloaded course videos after access ends?
Only if the provider’s terms and any institutional rules permit it. A technical ability to copy is not permission to retain or redistribute.
What is the safest first cleanup move?
Inventory and verify. When supported and appropriate, making verified cloud files online-only is more reversible than deleting them merely to regain local capacity.
