Enable or Disable Offline Files in Windows

Updated 7 November 2026 · Standard formula, shown below

To enable or disable Offline Files in Windows, open Control Panel, go to Sync Center, and click “Manage offline files.” From there, you can enable or disable the feature with a single button, and you must restart your computer for the change to take effect. This article walks you through the exact steps for Windows 10 and 11, explains what Offline Files does, and answers common questions about using it safely.

What Are Offline Files?

Offline Files is a Windows feature that lets you keep local copies of files and folders that live on a network share (like a company server or a NAS). When you disconnect from the network, you can still open, edit, and save those files. The next time you reconnect, Windows syncs your changes back to the server. It is especially useful for laptop users who travel or work from home with spotty connections.

The feature is built into Windows 10 and 11 Pro, Enterprise, and Education editions. It is not available in Windows 10/11 Home. If you have Home, you can still access network folders, but you won’t get the offline caching and sync behavior.

How Offline Files Works

When you enable Offline Files, Windows creates a local cache on your hard drive (usually in C:\Windows\CSC). It then monitors the network folders you mark as “always available offline.” The sync engine tracks changes both locally and on the server, using a database to resolve conflicts.

Two sync modes exist:

On-demand sync – Windows only downloads a file when you open it. This saves disk space but means you might not have a file available if you disconnect before opening it.
Always available offline – Windows pre-downloads the entire folder or file, so everything is available even without a network connection. This uses more disk space but guarantees access.

By default, Windows uses on-demand sync for most folders. You can right-click any network folder and select “Always available offline” to force a full download.

How to Enable Offline Files

Follow these steps to turn on Offline Files:

Open Control Panel (press Win + R, type control, and press Enter).
Click Sync Center. If you don’t see it, change the view to large or small icons.
In the left pane, click Manage offline files.
In the Offline Files dialog, click Enable Offline Files.
Click OK and restart your computer.

After restarting, you can right-click any network folder and choose Always available offline to start caching it.

How to Disable Offline Files

Disabling is just as simple, but be careful: turning it off deletes the local cache. Any changes you made while offline that haven’t synced will be lost.

Open Control Panel → Sync Center → Manage offline files.
Click Disable Offline Files.
Click OK and restart.

If you want to keep your cached files but stop syncing, you can instead remove the “Always available offline” setting from each folder. That leaves the feature enabled but stops caching new content.

When Should You Use Offline Files?

Offline Files is a good fit if you:

Work on a laptop and frequently move between locations with unreliable network access.
Need to access files from a server or NAS while traveling.
Want to keep working during a network outage without interruption.

It is not ideal if you:

Work with very large files (like video edits) that would fill your local disk.
Share a computer with others who might not understand offline caching.
Use network folders that are already synced by another tool (like OneDrive or Dropbox) – that can cause conflicts.

Common Problems and Troubleshooting

Here are issues people run into and how to fix them:

Files won’t sync – Check that you’re connected to the network and that the server is reachable. Open Sync Center and look at the sync results. Sometimes a conflict needs manual resolution.
Disk space running out – The cache can grow large. You can limit the cache size in the Offline Files dialog under the “Disk Usage” tab. Windows won’t let you set it below a certain minimum, but you can shrink it.
Encrypted files not available offline – Offline Files doesn’t support EFS (Encrypting File System) on some editions. Use BitLocker instead if you need encryption.
Can’t enable because of Group Policy – In managed environments, IT might disable Offline Files via Group Policy. You’ll see a message saying the feature is disabled by policy. You can’t override that without admin rights.

Offline Files vs. OneDrive and Other Sync Tools

Offline Files is often confused with cloud sync services like OneDrive, Google Drive, or Dropbox. The key difference is where the data lives:

Offline Files – Works with any network share (SMB/CIFS). The primary copy stays on your company server or NAS. You only cache a copy locally.
OneDrive/Google Drive – The primary copy is in the cloud. Your local folder is a mirror, and sync is always on (unless you set files to online-only).

If you use both, you might end up with two copies of the same file and potential sync conflicts. It’s usually best to pick one method per folder.

Frequently Asked Questions

Does Offline Files work with Windows 11 Home?

No. Offline Files is only available in Windows 11 Pro, Enterprise, and Education. Home edition does not include the Sync Center or the Offline Files feature.

Will disabling Offline Files delete my local copies?

Yes. When you disable the feature, Windows removes the local cache. Any unsynced changes are lost. Make sure you’re connected to the network and sync everything before disabling.

Can I use Offline Files with a USB drive or external hard drive?

No. Offline Files only works with network shares (SMB protocol). It does not apply to locally attached drives.

How do I know if a file has synced?

In File Explorer, right-click the file and select “Properties.” On the “Offline Files” tab, you’ll see its status (available offline, synced, or pending). You can also view sync results in Sync Center.

What happens if two people edit the same offline file?

Windows will detect a conflict during sync. It keeps both versions and asks you to choose which to keep, or you can merge them manually. To avoid this, coordinate with teammates or use a check-in/check-out system if your server supports it.

Can I change the cache location?

No. The cache is always in C:\Windows\CSC. You can’t move it to another drive, but you can limit its size in the Disk Usage tab.
