Windows 11 has garnered mixed reviews from users, particularly regarding its File Explorer, which has been a source of frustration for many. Despite the operating system’s overall improvements, minor annoyances can overshadow its strengths. One such annoyance is the unpredictable delay in opening folders, especially when using high-performance hardware like SSDs and powerful CPUs. This delay often stems from File Explorer’s Automatic Folder Type Discovery feature, which has been a part of Windows since the XP era.
File Explorer’s Folder Type Discovery feature causes occasional stutters
This feature attempts to enhance user experience by scanning folder contents to determine the most suitable view. However, when dealing with folders containing numerous files, such as game mod folders, the scanning process can lead to frustrating delays. Users can disable this feature, as it often provides unnecessary information—like the duration of media files—that can be accessed through file properties if needed. After disabling it, many users report a significant reduction in the time it takes for folders to open.
What’s actually going on under the hood?
Every time a folder is accessed, File Explorer samples its contents, analyzing file types and metadata to classify the folder into predefined templates. This classification process can slow down access times, particularly with large or mixed-content folders. While Automatic Folder Type Discovery aims to streamline organization, its execution can be counterproductive, especially on modern SSDs where the extra processing time becomes apparent.
A quick registry edit turns off this legacy Windows feature
For those looking to disable this feature, a simple edit in the Windows Registry Editor is required. Users should proceed with caution, as incorrect changes can lead to system issues. First, it’s advisable to back up the registry by navigating to File → Export and saving a copy. Then, users can access the necessary path in the Registry Editor: HKEYCURRENTUSER > Software > Classes > Local Settings > Software > Microsoft > Windows > Shell > Bags > AllFolders > Shell. By creating a new string value named FolderType and setting its value to NotSpecified, the feature can be effectively disabled.
A quick reboot later, Automatic Folder Type Discovery will be disabled
After making the registry changes, a quick restart of the PC or a reboot of File Explorer is all that’s needed to implement the changes. Users can restart File Explorer through the Task Manager, ensuring that the Automatic Folder Type Discovery feature is no longer active. While this adjustment may not drastically increase the speed of Windows Explorer, it does eliminate those annoying delays that can occur when accessing folders, particularly in high-pressure situations.
