How to Set Up a Shared Folder for a Small Team Without a Server

You Do Not Need Server Hardware for This

A persistent misconception in small offices is that shared folders require a server — a dedicated machine running Windows Server, or at minimum a NAS appliance. For a team of 2–8 people, that is not true. Any Windows 10 or 11 machine on the office network can host a shared folder that all team members access.

The catch is that the machine hosting the folder needs to be powered on when colleagues want to access it. If that is acceptable — and in most small office setups it is, since at least one machine runs during work hours — the built-in Windows sharing approach is entirely sufficient.

Step 1 — Choose the Host Machine

Select the machine that is most reliably on during working hours. This does not need to be a dedicated machine — a staff member's primary workstation works fine as long as it stays on.

If no reliable machine exists, consider:

• Setting the host machine's power settings to prevent sleep: Settings → System → Power → Screen and sleep → Never (when plugged in)
• Enabling Wake-on-LAN if the machine needs to be off during evenings but accessible in the morning before its owner arrives

Step 2 — Create the Folder Structure

On the host machine, create a root folder for shared content. Keep it on a drive other than C: if possible (less affected by OS reinstalls):

D:\Shared\
  └── Projects\
  └── Templates\
  └── Documents\
  └── Resources\

The exact structure does not matter — use what reflects how your team thinks about files.

Step 3 — Set the Network Profile to Private

Sharing only works reliably on Private networks. On the host machine:

1. Open Settings → Network and Internet
2. Click your active connection (WiFi or Ethernet)
3. Under Network profile type, select Private network

Step 4 — Enable File and Printer Sharing

1. Open Settings → Network and Internet → Advanced network settings → Advanced sharing settings
2. Under Private networks, turn on:
   • Network discovery
   • File and printer sharing
3. Under All Networks, consider whether to keep Password protected sharing on or off:
   • On (recommended): users need credentials to access the share
   • Off: any machine on the network can access shared folders without authentication

Step 5 — Share the Folder

1. Right-click the root shared folder (e.g., D:\Shared) → Properties
2. Go to the Sharing tab → click Advanced Sharing
3. Check Share this folder
4. Set the Share name (this is what colleagues will type to connect; keep it simple: Shared)
5. Click Permissions:
   • To allow everyone to read and write: add Everyone, set permissions to Full Control
   • To restrict: add specific user accounts with specific permissions
6. Click OK and Apply

Step 6 — Connect From Other Machines

On each colleague's machine:

Option A — Browse: Open File Explorer → left sidebar → Network → find the host machine → open the Shared folder

Option B — Direct address: Open File Explorer → address bar → type \\HOSTNAME\Shared → press Enter (Replace HOSTNAME with the host machine's computer name, visible in Settings → System → About)

Option C — Map as a permanent drive:

1. Open File Explorer → right-click This PC → Map network drive
2. Choose a drive letter (e.g., Z:)
3. Enter \\HOSTNAME\Shared
4. Tick Reconnect at sign-in
5. Click Finish

The shared folder will appear as Z: (or your chosen letter) every time Windows starts.

Handling Authentication

If password-protected sharing is enabled, Windows will prompt for credentials when a colleague first connects. They should enter a username and password that exists as a local account on the host machine.

For simplicity across a small team: create one shared local account on the host machine (e.g., officeuser with a shared password). All team members use these credentials. More granular access control — per-user, per-folder — requires individual accounts per person.

When to Upgrade to a NAS

The single-host Windows share approach has one meaningful limitation: it depends on one person's machine being on. When that machine goes in for repairs, gets taken home, or gets upgraded — the shared folder is unavailable.

A NAS device (Synology, QNAP) is always on, does not depend on any particular person's machine, and provides better access logging. For teams that have been using the above setup for a while and keep running into the "host machine is off" problem, a NAS is the right next step.

For day-to-day file handoffs between colleagues that do not require a permanent shared location, a LAN transfer tool removes the dependency on the host machine entirely. Oxolan handles peer-to-peer transfers within your network, with no shared folder configured on either side.

Frequently Asked Questions

Does this work over WiFi or only wired? It works over WiFi. Wired connections are faster for large file transfers but the setup process is identical.

How many people can connect to a shared folder simultaneously? Windows 10 and 11 Home allow up to 5 simultaneous connections; Pro and above allow up to 20. For most teams of 2–8 people, this is sufficient.

What happens to the shared folder if the host machine restarts? Shared folders are re-enabled automatically after restart; the mapped drive on colleagues' machines reconnects. If you have required credentials and the host machine finished starting before colleagues log in, authentication happens automatically using stored credentials.

Can I access the shared folder from home? Not directly — the folder is only accessible on the local network. Options for remote access include: setting up a VPN back to the office network, or syncing the shared folder to a cloud service as a secondary backup that remote workers access.
