File Explorer on your Windows computer is slow to open or freezes
File Explorer is slow because either your hard drive is being hammered by Windows scanning files, or too much is set to preview in folder view. Turn off Quick Access in File Explorer settings and disable file previews — this fixes it for most people. If that doesn't work, restart File Explorer from Task Manager.
Windows File Explorer caches information about your files to make browsing faster, but sometimes it gets stuck trying to scan large folders or perform antivirus checks. Other times, the preview feature in File Explorer is trying to load thumbnails for every file at once. The quickest fix is to disable Quick Access and turn off preview features. If it's still slow, restarting File Explorer clears out whatever is stuck.

Skip — I just want a technicianCommon mistakes to avoid
- Disabling all options in Quick Access without realizing you can still browse your files — Quick Access is just a shortcut, not your only way to find files
- Thinking you need to delete all files to free up space — cleaning up old Downloads and Recycle Bin gives you back enough space in most cases
- Assuming the problem is File Explorer when it's actually a cloud app syncing in the background — check your system tray for OneDrive or Google Drive icons
Signs you need professional help
- You've disabled previews and freed up drive space, but File Explorer is still freezing — your hard drive is probably failing
