Shared drives are unglamorous and a little old-fashioned, but they're also something every person in your office understands immediately. SharePoint is more powerful, more flexible, and more integrated with the rest of Microsoft 365 — and it requires a lot more intentional setup to work well.
Neither answer is right for every firm. Here's how to think about the choice.
When shared drives still make sense
A traditional file server or mapped drive works well when your team's workflow is simple and stable — everyone accesses the same folder structure, files are mostly project-based, and nobody needs to collaborate on documents in real time.
If that describes your firm and your current setup works, there's no urgent reason to move. The migration overhead and learning curve of SharePoint may not be worth it.
When SharePoint is genuinely better
SharePoint's advantages become real in a few specific situations:
Remote and hybrid work. SharePoint files are accessible from any device without a VPN. For firms with hybrid teams or people who work from multiple locations, this removes real friction.
Document collaboration. When multiple people need to work on the same document, SharePoint with co-authoring is significantly better than a shared drive where someone inevitably has the file locked.
Integration with Teams. Each Teams channel has a SharePoint folder behind it. If you're using Teams for project communication, having project files in the same structure makes sense.
Permissions complexity. SharePoint's permissions model is more granular than most file servers. If you need different access levels for different projects or client files, SharePoint handles this better.
When SharePoint won't work
Some applications simply can't use SharePoint as a live data location. Autodesk Revit is the most common example in professional services firms — it requires files to be on a local or mapped network drive, and attempting to work with Revit models stored directly in SharePoint causes file corruption and sync conflicts. The same is true of several other design and database applications that hold files open for extended periods.
If Revit or similar software is central to how your team works, a shared drive (or a hybrid approach where project work stays on a file server while other documents move to SharePoint) is not optional — it's the only configuration that works reliably.
The catch with SharePoint
SharePoint requires governance to work. "Just put the files in SharePoint" is not a migration strategy. Without a clear folder structure, naming conventions, and some training, it degrades into something worse than the shared drive you left.
Firms that have bad SharePoint experiences usually had one of two problems: they migrated without structuring it first, or they let too many people create sites and folders without any coordination.
The good news is that the governance overhead isn't enormous — it just has to happen before the migration, not after.
A practical approach
If you're evaluating a move, start by asking how much of your work is truly collaborative versus individual. If most of your work is one person on one file, the advantages of SharePoint are smaller. If your team regularly hands documents back and forth or needs simultaneous access, the benefits are more immediate.
Either way, a migration is worth planning deliberately rather than treating as a simple lift-and-shift.
