File Explorer Not Responding: How to Fix It

When File Explorer not responding messages appear, the quickest fix is to restart Windows Explorer: press Ctrl + Shift + Esc, find Windows Explorer under Processes, right-click it and select Restart. If it keeps freezing, the cause is usually an unreachable network or cloud location, a heavy folder of thumbnails, a third-party context-menu add-on or damaged system files, and each has a specific fix below.

The steps apply to Windows 11 and Windows 10. Work through them in order; most people are sorted by the first four.

Why Is My File Explorer Not Responding?

File Explorer stops responding when something it is waiting for does not answer. Explorer is a single program that draws your folders, desktop and taskbar, so when one task inside it stalls, the whole window can freeze.

How Do You Restart Windows Explorer?

Restarting Windows Explorer reloads File Explorer, the taskbar and the desktop without restarting the PC, and it clears most temporary freezes in seconds.

1. Press Ctrl + Shift + Esc to open Task Manager.
2. On the Processes page, find Windows Explorer.
3. Right-click it and select Restart. The taskbar disappears briefly, then returns.
4. If the taskbar does not come back, select Run new task in Task Manager, type explorer.exe and press Enter.

If restarting fixes it only for a while, keep going: something is repeatedly triggering the freeze.

How to Clear File Explorer History and Open to This PC

Clearing File Explorer history fixes freezes caused by a long list of recent files, particularly ones stored on drives or cloud locations that are no longer available. File Explorer tries to check each item before it can draw the window.

1. Open File Explorer, select See more (the three dots) on the toolbar, then Options. On Windows 10, select View → Options.
2. On the General tab, under Privacy, select Clear.
3. Set Open File Explorer to to This PC.
4. Untick the options to show recently used files and frequently used folders if you do not need them.
5. Select OK and reopen File Explorer.

Microsoft recommends Home as the landing page because it shows recent and cloud files together, but This PC loads faster on systems where those sources are slow.

How to Stop Thumbnails and Previews from Freezing Folders

Turning off thumbnails and the preview pane stops File Explorer reading every image and video in a folder before it displays it. A folder with thousands of large photos, or one damaged video file, can stall the whole window.

1. In File Explorer, select View and make sure the Preview pane and Details pane are off. On Windows 11, they are under View → Show.
2. Open See more → Options and select the View tab.
3. Tick the option to show icons instead of thumbnails.
4. Tick Launch folder windows in a separate process, so one stuck window does not freeze the others.
5. Select Apply, then OK.

To clear old thumbnails that may be corrupt, run Disk Cleanup on drive C: and tick Thumbnails. Windows rebuilds them as you browse.

Could Network Drives, OneDrive or USB Devices Be the Cause?

Yes. File Explorer waits for every drive listed under This PC, so an unreachable mapped network drive or a USB device with errors can hold up the entire window.

• Mapped network drives: right-click a drive with a red cross and select Disconnect, then remap it when the server is reachable.
• OneDrive and other cloud apps: pause syncing from the cloud icon in the notification area and test again. If the freeze stops, update or reset the sync app.
• USB drives: unplug external drives and card readers one at a time. A failing drive often makes Explorer hang the moment it is connected.

If a USB drive is not showing up in File Explorer at all, right-click Start → Disk Management. If the drive appears there without a letter, right-click its partition and choose Change Drive Letter and Paths → Add. Do not initialise or format a drive that holds data you need.

How Do You Find a Faulty Shell Extension?

A clean boot finds a faulty shell extension, which is a third-party add-on that plugs into File Explorer's right-click menu, previews or icons. Archive tools, cloud clients, graphics utilities and older security software commonly add them, and one buggy add-on can freeze Explorer whenever you right-click.

1. Press Windows + R, type msconfig and press Enter.
2. On the Services tab, tick Hide all Microsoft services, then select Disable all.
3. Open Task Manager's Startup apps page and disable the third-party apps listed there.
4. Restart and test File Explorer.
5. If the problem is gone, re-enable items in small groups until it returns. The last group you enabled contains the culprit.
6. Update or uninstall that app, then return msconfig to Normal startup.

Our guide to managing Windows 11 startup programs explains the startup list in more detail.

How to Repair System Files When File Explorer Keeps Crashing

If File Explorer still crashes after the steps above, repair Windows system files with DISM and the System File Checker. Microsoft's System File Checker guide recommends running DISM first so SFC has healthy files to copy from.

1. Right-click Start and select Terminal (Admin).
2. Run DISM.exe /Online /Cleanup-image /Restorehealth and wait for it to finish.
3. Run sfc /scannow.
4. Restart the PC when both complete.
5. Install pending updates from Settings → Windows Update.

Our DISM RestoreHealth guide explains what to do if DISM reports errors. If nothing helps, a Windows 11 repair install replaces every system file while keeping your apps and files.

A Common Mistake We See

The most common mistake is reinstalling Windows to fix a freezing File Explorer when the real cause is outside Windows: a dead mapped drive, a sync app stuck on one file, or a context-menu add-on. A reinstall removes the symptom only until the same app or drive is added back. Spend ten minutes on the clean boot and drive checks first.

We also see Windows 10 PCs with this problem that have not had updates since support ended on 14 October 2025. Windows 11 continues to receive quality fixes for Explorer, while Windows 10 PCs enrolled in Extended Security Updates receive security fixes only, so moving to Windows 11 is the long-term answer.

Frequently Asked Questions

Why does Windows Explorer stop responding when I right-click?

A right-click freeze usually comes from a third-party context-menu add-on. Each installed app can add entries to that menu, and Explorer waits for all of them. Perform a clean boot to identify the app, then update or remove it.

How do I fix Windows 10 File Explorer not responding?

The fixes are the same as on Windows 11: restart Windows Explorer in Task Manager, clear history in View → Options, disconnect missing network drives, turn off previews and run DISM and SFC. Windows 10 no longer receives free updates, so persistent bugs may not be fixed there.

Is File Explorer not responding a sign of a virus?

Rarely. Most freezes come from drives, add-ons, thumbnails or damaged system files. Still, run a full scan in Windows Security → Virus & threat protection if the freezes started suddenly alongside pop-ups, unknown apps or a slow PC.

Why is my USB not showing up in File Explorer?

The drive may have no drive letter, an unreadable file system or a hardware fault. Check Disk Management: if it appears there, assign a letter. If it does not appear anywhere, try another port and cable, then test it on a different PC.

Can low disk space make File Explorer freeze?

Yes. When the system drive is nearly full, Windows struggles to create temporary and paging files, and Explorer slows down or hangs. Keep at least 10 to 15 percent of drive C: free, and use Disk Cleanup or Storage Sense to recover space.

Why does File Explorer freeze on one folder only?

That folder usually contains a damaged file, very large media or a huge number of items. Switch the folder to the Details layout, turn off thumbnails and the preview pane, then move suspect files elsewhere to find the one causing the hang.

Conclusion

File Explorer not responding is usually fixable in minutes: restart Windows Explorer, clear history, check drives and add-ons, then repair system files if needed. A reinstall should be the last resort, not the first. If your PC is still on an unsupported version, our Windows 11 licences keep it on a fully updated system.
