Windows 11 File Explorer lag can be caused by several factors, including too many quick access records, slow loading of the preview pane, high disk usage, graphics card or chipset driver issues, and corrupted system files. It is recommended to first clear the File Explorer cache, then check the disk and drivers, and finally repair system components.
1. Restart File Explorer
If File Explorer freezes, restart it first. Here’s how:
1. Press Ctrl + Shift + Esc to open Task Manager ;
2. Locate “Windows Explorer” , right-click and select “Restart” ;
3. Wait for the desktop to refresh;
4. Reopen the folder to test.
II. Clearing Fast Access Records
Quick access saves frequently used files and folders; saving too many may slow down opening speed. How to use:
1. Open File Explorer and click the “…” in the upper right corner ;
2. Go to “Options” , find “Privacy” , and click.“Clear” ;
3. Then uncheck ” Show recently used files ” and ” Show frequently used folders “.
After cleaning, reopen File Explorer and see if it’s faster.
3. Update drivers
If File Explorer freezes after a system update, graphics card driver update, hard drive replacement, or use of external devices, you can first use Driver Booster to check for related drivers such as the graphics card driver, motherboard chipset, and storage controller. Steps:
1. Click below to install and open Driver Life on your computer;

3. If an error message or an outdated version is displayed, follow the prompts to repair.
4. After restarting your computer, open File Explorer again to test.
IV. Check disk usage
Slow file explorer loading may also be due to high disk usage. Here’s how:
1. Right-click the taskbar and open Task Manager ;
2. Click “Performance” to check disk usage;
3. If the disk usage remains at 100% for an extended period, first close large software programs, cloud storage synchronization, and antivirus scans;
4. Hard drive users can check the health status of their hard drives.
V. Repair system files
If all folders are experiencing slowdowns, it may be due to abnormal system files. Here’s how:
1. Open “Command Prompt” as an administrator ;
2. Type: sfc /scannow and press Enter ;
3. Wait for the scan to complete;
4. Restart your computer.
5. If the problem persists, you can reopen the command prompt, enter the following command, and press Enter:
DISM /Online /Cleanup-Image /RestoreHealth
The biggest mistake when File Explorer lags is blindly cleaning up system files. A more reliable approach is to first distinguish between “all folders are slow” and “a specific folder is particularly slow”: for the former, focus on system components, disk, and drivers; for the latter, focus on the number of files, thumbnails, and preview loading. Identifying the problem before taking action will be much more efficient.
