Windows 11 users can enhance File Explorer's performance by disabling its automatic folder type discovery, which is known to cause lag. This adjustment is particularly useful for folders with a large number of items.
Registry Modification Instructions
Users can modify the registry to force a generic folder view. It's crucial to back up the registry first (go to Registry Editor > File > Export > All) to ensure safety. Access
Create a new String Value named FolderType and set its value to NotSpecified. Restart Windows Explorer (Task Manager > find Windows Explorer > Right-click > Restart) to apply changes without needing to reboot the system.
Alternative Methods and Reversal
Alternatively, run PowerShell as an administrator and execute: Set-ItemProperty -Path 'HKCU:\Software\Classes\LocalSettings\Software\Microsoft\Windows\Shell\Bags\AllFolders\Shell' -Name 'FolderType' -Value 'NotSpecified' -Type String. A third option involves creating a .reg file with the specified content and merging it.
To revert to automatic folder type detection, delete the FolderType value from the same registry path. Always ensure the registry is backed up before making any changes.
