"We already have a shared drive and it works fine. Why do we need SharePoint?"
It's a completely reasonable question. If your organisation has used a file server or Dropbox for years and people know where everything is, the argument for changing isn't obvious. This article explains the concrete differences — not the marketing ones, but the ones you notice day to day.
What they have in common
To be fair: both a shared drive and SharePoint let you save files and access them from different computers. If that's all you need, a shared drive works.
The problem is that organisations rarely need only that.
Search — the most visible difference
Shared drive: Search looks for filenames. If you can't remember what the document is called, you have to navigate through folders until you find it — or don't.
SharePoint: Search indexes the content of documents. You can search by words that appear inside the file, by metadata (client, status, date), by document type, by author. "Show me all contracts with Acme Ltd from last year" — without remembering the filename.
For organisations with hundreds or thousands of documents, this difference is enormous in daily productivity.
Copilot AI — only works with SharePoint
This is perhaps the most relevant difference looking ahead. Microsoft Copilot — the AI assistant integrated into Microsoft 365 — works with content that's in SharePoint and OneDrive.
If your documents are in a shared drive on a local server or in Dropbox, Copilot can't access them. It can't summarise a contract that lives on the file server. It can't answer "what's our returns policy?" if that policy is in a network folder.
With documents in SharePoint, Copilot can:
- Summarise long documents in seconds
- Answer questions about the content of your files
- Draft documents based on existing information in your organisation
- Find relevant information across multiple documents at once
Moving documents to SharePoint isn't just an organisational decision — it's preparing the organisation for AI tools that are already available.
Versioning — never again "which one is the right one?"
Shared drive: If two people edit the same document, one overwrites the other's work. Or worse — each saves their version under a different name and five versions of the same document end up existing.
SharePoint: Every time someone saves a document, SharePoint automatically saves a previous version. You can see the full change history, who did what and when, and restore any previous version in seconds. One file, one single source of truth, with its entire history preserved.
Access from anywhere
Local server shared drive: Only accessible from the office or via VPN. If someone is working from home or travelling, they need a configured and working VPN connection.
SharePoint: Accessible from any browser, from a mobile phone, from any computer — no VPN, just Microsoft 365 credentials. The same document, the same version, from anywhere.
Permissions — granular and auditable
Shared drive: Permissions are managed at the folder level on the server. It works, but it's hard to audit, hard to scale, and leaves no trace of who has accessed what.
SharePoint: Permissions are granular — by site, by library, by folder, or by document. You can give a supplier read access to one specific folder without them seeing anything else. And you can audit who accessed what and when — particularly important for GDPR compliance.
Automation — only possible with SharePoint
With a shared drive, processes are always manual. Someone uploads the contract, someone notifies the owner by email, someone reviews it, someone approves it.
With SharePoint and Power Automate:
- When a contract is uploaded, it's automatically sent to the owner for review
- When it's approved, the client receives an automatic notification
- When it's about to expire, the owner receives a reminder
- Everything is recorded without manual intervention
Automation doesn't require programming — Power Automate has a visual interface that anyone with basic knowledge can use.
Co-authoring — editing together in real time
Shared drive: One person at a time. If someone has the document open, everyone else has to wait or risk version conflicts.
SharePoint: Multiple users can edit the same document simultaneously in real time, seeing each other's changes instantly — just like Google Docs but with the full power of Microsoft Office.
The cost — you're already paying for it
If your organisation has Microsoft 365 (formerly Office 365), SharePoint is already included in your subscription. It's not an additional cost. Every Microsoft 365 user has access to SharePoint, Teams, OneDrive, and the rest of the suite.
If you're still running a local file server on top of paying for Microsoft 365, you're paying for two solutions when you could use just one.
When does a local server still make sense?
There are cases where a local server still makes sense — organisations with very specific compliance requirements that demand data on their own premises, or sectors with regulations that require it. But for most mid-sized organisations, these cases are exceptions.
The summary
| Shared drive | SharePoint | |
|---|---|---|
| Content search | ❌ | ✅ |
| Copilot AI compatible | ❌ | ✅ |
| Version history | ❌ | ✅ |
| Access from anywhere | ❌ (requires VPN) | ✅ |
| Real-time co-authoring | ❌ | ✅ |
| Auditable permissions | Limited | ✅ |
| Process automation | ❌ | ✅ |
| Additional cost with M365 | N/A | Included |
If your organisation already has Microsoft 365, the question isn't whether you can afford SharePoint — you're already paying for it. The question is when you're going to start using it properly.
