Summary
This article explains the difference between traditional network drives (mapped drives like H: or S:) and cloud storage (OneDrive and SharePoint) so you can choose the right place to save your files. Many organizations are transitioning from network drives to cloud storage, and understanding when to use each option prevents data loss, access issues, and confusion.
Prerequisites
- A Windows 10 or Windows 11 computer.
- A Microsoft 365 account with OneDrive access (for cloud storage sections).
- Access to your organization's network drives (if applicable).
Instructions
1. What Are Network Drives?
A network drive (also called a "mapped drive" or "shared drive") is a folder stored on a physical server in your organization's office or data center. It appears in File Explorer as a drive letter, such as:
- H: — Your personal home drive (accessible only to you).
- S: or G: — A shared/group drive (accessible to your team or department).
- P: — A project drive.
How they work:
- Files are stored on a server physically located in your office (or a data center).
- A connection to the company network (either in the office or via VPN) is required to access them.
- IT manages backups, permissions, and server maintenance.
2. What Is Cloud Storage (OneDrive and SharePoint)?
Cloud storage keeps your files on Microsoft's servers, accessible from anywhere with an internet connection.
- OneDrive — Your personal cloud storage (like a cloud version of the H: drive). Files are private to you unless you share them.
- SharePoint — Team/department cloud storage (like a cloud version of the S: drive). Files are shared with your team, and every Teams channel has a SharePoint document library behind it.
How they work:
- Files are stored in the Microsoft 365 cloud.
- You can access them from any device (office PC, home laptop, phone, tablet) via browser, desktop app, or mobile app.
- Files can be synced to your computer for offline access using the OneDrive sync client.

4. Decision Guide — Where Should I Save This?
"It's a personal file only I need." → OneDrive. This is your personal cloud space. It syncs across devices and is backed up automatically.
"My team needs to access and collaborate on this file." → SharePoint (or the Files tab in a Teams channel). Everyone on the team can view, edit, and co-author in real time.
"I need to work on this file offline at home." → OneDrive or SharePoint with sync enabled. The OneDrive sync client keeps a local copy on your computer that syncs when you are back online.
"This file is a large dataset or specialized application file." → Network drive (if still in use). Some legacy applications and very large files perform better on a local network server than cloud storage.
"I need to share this file with someone outside the organization." → OneDrive or SharePoint sharing link. Network drives cannot be shared externally.
"The file must stay on-premises for compliance reasons." → Network drive (or whatever IT has designated for compliance data). Some regulated industries require certain data to stay on local servers. If you are not sure which location is approved for the file in front of you, ask IT to confirm the correct path for that type of data before you save it anywhere.
5. How to Access Network Drives
If the Drive Is Already Mapped
- Open File Explorer (press Win + E).
- Look in the left sidebar under This PC — your mapped drives appear with their letters (e.g., H:, S:).
- If working from home, connect to VPN first, then open File Explorer.
If the Drive Is Not Mapped
- Open File Explorer.
- Click This PC in the left sidebar.
- Click the three-dot menu (⋯) (Windows 11) or Computer tab (Windows 10) and select Map network drive.
- Choose a drive letter and enter the network path (UNC path) provided by IT, such as
\\server\shared\department. - Check Reconnect at sign-in to keep the mapping persistent.
- Click Finish.

6. How to Access OneDrive and SharePoint
- OneDrive: Open File Explorer — your OneDrive folder appears in the left sidebar. Or go to
onedrive.com. - SharePoint: Go to your SharePoint site in a browser, or access files through the Files tab in a Teams channel.
- Sync to File Explorer: In SharePoint or OneDrive web, click Sync to add the library to your File Explorer for offline access.

7. Common Migration Scenarios
Many organizations are moving from network drives to cloud storage. Here is what to expect:
| Old Location | New Location | What Happens |
|---|---|---|
| H: drive (personal) | OneDrive | Your personal files are migrated to OneDrive. You access them via File Explorer or onedrive.com. |
| S: or G: drive (shared) | SharePoint / Teams | Department files are migrated to a SharePoint site or Teams channel Files tab. |
| Project folders on a file server | SharePoint site | A dedicated SharePoint site is created for each project. |
DANGER
During a migration, IT will provide a timeline and instructions. Do not move files yourself unless instructed — premature moves can cause permission issues and broken links. If you notice missing files after a migration, contact IT immediately.
Troubleshooting
TIP
If you are unsure where to save a file, the safest default is OneDrive for personal files and the Teams Files tab (which is SharePoint) for team files. This ensures your files are backed up, versioned, and accessible from anywhere.
| Symptom / Error | Potential Cause | Solution |
|---|---|---|
| Network drive is not visible in File Explorer | Not connected to VPN or drive mapping was lost | Connect to VPN and remap the drive (Step 5). If it still does not appear, ask IT to confirm the file server is online and that your drive mapping is still assigned to you. |
| "The network path was not found" | VPN not connected, server offline, or wrong path | Verify VPN connection. Confirm the UNC path with IT. |
| OneDrive sync icon shows red X | Sync conflict or file path too long | Click the OneDrive icon in the system tray to see the error. Shorten file names if path exceeds 400 characters. |
| Cannot find migrated files | Files were moved to a new SharePoint location | Contact IT for the new file location. Check your Teams channel Files tabs. |
| Files on network drive are very slow | VPN bandwidth limitation or server load | Copy the file locally, work on it, then copy it back. Consider migrating to OneDrive/SharePoint for better remote performance. |
