SharePoint vs file server: which one to choose?

SharePoint vs file server: the question comes up when the server reaches the end of its life, or when remote work becomes common. Both store documents, but they do not work the same way, and a poorly prepared migration leaves users lost and permissions inconsistent.

This guide compares the two approaches on the criteria that matter for an SME in Switzerland: collaboration, access rights, remote access, large files and business applications, then covers migration and the hybrid model.

What changes between SharePoint and a file server?

A file server presents folders on a network drive, accessible in the office or remotely through a VPN. SharePoint, included in Microsoft 365, organizes documents into sites and libraries, accessible from a browser, from Teams or from Windows File Explorer through OneDrive sync.

The most visible difference is co-authoring: several people edit the same Word or Excel document at the same time, with a version history. On a file server, the first person to open a document locks it for everyone else.

Permissions and sharing: what are the differences?

On a server, permissions are set folder by folder, often over the years, until nobody understands the structure anymore. SharePoint works best with simple permissions set at the site or library level: one site per team or activity, members, an owner.

SharePoint also lets you share a file with an external person. It is convenient, but it needs rules: decide who can share externally, with which type of link and for how long. Permissions inherited from an old server are rarely worth carrying over as they are: this is the opportunity to simplify them.

When does a file server still make sense?

• Very large files opened directly from the network: CAD drawings, layouts, video.
• Business applications that require a network path or a drive letter, for example a database stored in a shared folder.
• A slow or unreliable Internet connection at the site.
• Folder structures with very long paths or a very large number of files, which cause problems for sync.

OneDrive sync: what you need to know

OneDrive sync shows SharePoint libraries in File Explorer, like a local folder. With Files On-Demand, only the documents you open are downloaded to the computer.

It has its limits: some characters are not allowed in file names, paths that are too long get blocked, and syncing very large libraries slows computers down. It is better for each person to sync only what they need.

Migrating to SharePoint or adopting a hybrid model

A successful migration starts with sorting: archive what is no longer used, review the folder structure and permissions rather than copying everything as is. Then come the data copy, a period during which the old share becomes read-only, and support for the teams.

Many SMEs adopt a hybrid model: SharePoint and Teams for everyday working documents, and a server, on site or hosted in a Swiss cloud, for large files and the business application. In every case, files must be backed up: Microsoft 365 ensures the service is available, not the long-term backup of your data.
