To find the Z drive on a Windows 10 work computer, open File Explorer, select This PC, and look among the computer’s drives or network locations. If Z: is missing, it may not be mapped for your signed-in account or may not be available until the work network connection is ready; check with IT before changing a company-managed mapping.
How to find the Z drive in Windows 10
- Open File Explorer. Select its taskbar icon, go to Start > File Explorer, or press Windows logo key + E.
- Select This PC in the left-hand pane.
- Look through the entries for drives and network locations. If Z: is assigned to your account and available, it should appear there.
- Double-click the Z drive to open it.
The label beside the drive may identify a department, server, or shared folder rather than saying “Z drive.” Check the drive letter shown beside the label.
Open Z: directly
If you know the drive is mapped but cannot immediately spot it in the list, use File Explorer’s address bar:
- Open File Explorer.
- Select the address bar at the top of the window.
- Type Z:\.
- Press Enter.
This opens the drive only when Z: is assigned and accessible in the current Windows session. If Windows reports that it cannot find or access the location, the drive may not be mapped, the remote computer may be off, or your account may not have permission.

Map the Z drive in Windows 10
If your employer has given you a shared-folder path, you can map that location to Z:. A shared-folder path uses UNC syntax, such as \\server\share or \\computer-name\shared-folder-name.
- Open File Explorer.
- Select This PC in the left pane.
- Select the Computer tab on the ribbon.
- Select Map network drive.
- In the Drive list, select Z:.
- In the Folder box, enter the shared-folder path, such as \\server\share. You can also select Browse.
- Select Reconnect at sign-in if the drive should be restored automatically whenever you sign in.
- Select Finish.
Use the exact server and share name supplied by your organization. A guessed path will not work unless that computer and shared folder exist and are available to you.
If “Map network drive” is not visible
Make sure This PC is selected, rather than a folder inside it. In Windows 10, the documented command is on the Computer tab. You can also right-click the This PC node in File Explorer’s folder pane and select Map network drive.
The route This PC > More > Map network drive describes the newer Windows 11 ribbon, not the standard Windows 10 interface.

Windows does not reserve Z: for network drives. The mapping dialog permits any available drive letter, so Z: could be a network share, local disk, removable storage, or a drive assigned by company policy.
If the Drive list does not let you select Z:, check This PC first. Another device or existing mapping may already be using that letter. Do not disconnect or replace a company-managed mapping without checking with your IT department. Your organization may use sign-in scripts or management software to restore it automatically.

Why the Z drive may be missing
| What you see | Likely explanation | What to check |
|---|---|---|
| Z: is not listed in This PC | It is not mapped in your current user session, uses another letter, or the sign-in or network mapping has not completed. | Reconnect to the work network, check all drives and network locations, and follow your organization’s sign-in process. |
| Z: produces an access error | The remote computer may be off, or your account may lack permission. | Confirm the computer or server is on and that you are connected to the required company network or VPN. Ask IT to verify access. |
| The server or share does not appear under Network | Network discovery may be turned off, or the computers may not be on the same network. | Check network discovery and confirm the connection is the expected work network. |
| The drive appears but folders cannot be opened | Your account may not have permission for the share or a particular folder. | Contact the owner or IT support rather than changing permissions yourself. |
Fix network discovery and sharing settings
If File Explorer displays a banner saying “Network discovery is turned off”, select the banner and then select Turn on network discovery and file sharing.
You can also check Windows 10 sharing settings through Start > Settings > Network & internet > Sharing options.
Under Private, select Turn on Network discovery and Turn on file and printer sharing. Under All Networks, Microsoft’s troubleshooting path includes selecting Turn off password protected sharing. On a work computer, check your organization’s policy before changing this setting; company security rules may require password-protected sharing to remain enabled.
For the documented sharing workflow, computers should be connected to the same network, and a Wi-Fi connection should be set to Private. A work laptop on another network may not discover the share.
Check the Windows services used for discovery
If network devices remain undiscoverable after checking sharing settings, Microsoft lists four services that should be running with Startup type: Automatic:
- Function Discovery Provider Host
- Function Discovery Resource Publication
- SSDP Discovery
- UPnP Device Host
To inspect them:
- Press Windows logo key + R.
- Type services.msc.
- Select OK.
- Find each service in the list and check its status and startup type.
On a company-managed computer, do not change service settings unless your IT department instructs you to do so. If a service is stopped or controlled by policy, report that information to support.
HomeGroup will not restore a missing Z drive
Older Windows instructions sometimes recommend HomeGroup for finding or reconnecting shared folders. That advice is obsolete. HomeGroup was removed from Windows 10 starting with version 1803 and cannot be used to create, join, or leave a HomeGroup.
In Windows 10 version 1803 and later, obsolete HomeGroup (view) or HomeGroup (view and edit) entries may still appear under Give access to, but they do nothing. Ordinary Windows network shares still work. If you know the share’s path, open it directly with a path such as \\homePC\SharedFolderName, or map that path to an available drive letter.
When to contact your company’s IT department
Ask IT for help if you do not know the correct server path, the Z drive disappeared after a password or account change, or the share requires a company VPN or sign-in process. Include:
- Your Windows username or department, if relevant
- Whether you are in the office or connected remotely
- Whether Z: is missing entirely or appears but cannot be opened
- The exact error message
- Whether other shared drives are working
Do not use a path or credentials supplied by an unknown source. A mapped drive gives access to shared files, and a wrong server path can expose or overwrite data you were not meant to use.
Windows 10 support status
Microsoft support for Windows 10 ended on October 14, 2025. Windows 10 continues to run, but Microsoft no longer provides the normal free Windows Update software updates, technical assistance, or security fixes after that date. On a work computer, the upgrade decision belongs to your organization, so follow your company’s device-management instructions rather than upgrading independently.

Where is the Z drive located in Windows 10?
Open File Explorer, select This PC, and look among the drives and network locations. If Z: is assigned to your signed-in account and available, it should appear there.
How do I open the Z drive without browsing to it?
Open File Explorer, select the address bar, type Z:\, and press Enter. This works only when Z: is currently assigned and accessible in that Windows session.
Why is my Z drive missing from This PC?
It may not be mapped for the current user, may use a different drive letter, or may not be available until the network connection or sign-in mapping completes.
The Tool Desk

Open File Explorer, select This PC, select the Computer tab, choose Map network drive, select Z:, enter the UNC path such as \\server\share, optionally select Reconnect at sign-in, and select Finish.
Is Z: always a network drive?
No. Windows allows any available drive letter to be used for local, removable, network, or policy-managed storage. The letter alone does not identify the drive type.
Can HomeGroup reconnect my Z drive?
No. HomeGroup was removed from Windows 10 beginning with version 1803. Use the shared folder’s UNC path or Map network drive instead.
The Bottom Line
Start with File Explorer > This PC. If Z: is listed, open it there or type Z:\ in the address bar. If it is missing, use the correct UNC path and This PC > Computer > Map network drive to map a share—but on a work computer, confirm the path and permissions with IT before changing an existing company mapping.
