Clean Up Windows 10: Remove the Unwanted 3D Objects Folder from This PC
Since the introduction of Windows 10, users have observed the presence of a new default folder labeled 3D Objects within the “This PC” section of File Explorer. This folder is integrated as a standard Library item and appears automatically upon installation. It serves as the designated default storage location for any 3D-related files or projects created or managed on your computer.
While Microsoft introduced this folder to support the growing ecosystem of 3D applications and content creation tools integrated into Windows 10, not all users engage with these features. For many, the 3D Objects folder remains perpetually empty and represents unnecessary clutter in a frequently accessed part of the operating system interface. Users who do not work with 3D models or applications like Paint 3D or Mixed Reality Viewer may find its persistent presence redundant and prefer a cleaner File Explorer layout. The desire to streamline the “This PC” view often leads users to seek methods for removing this default entry.
The 3D Objects folder typically stores files with the .3mf extension, which are commonly associated with 3D printing and modeling. These files can be opened and viewed using applications such as the built-in Mixed Reality Viewer in Windows 10. The physical location of this folder on your system is generally found at C:\Users\Username\3D Objects, where ‘Username’ corresponds to your specific user profile name. Although the folder itself is just a directory like Documents or Pictures, its prominence in the File Explorer navigation pane is controlled by specific system configurations, primarily managed within the Windows Registry. Removing the entry from File Explorer does not delete the folder’s contents on your hard drive, but it does hide the quick access link from the “This PC” view.
For users who find the folder’s presence undesirable, Windows 10 provides a way to remove this entry from the File Explorer interface. This process involves making modifications to the Windows Registry, a hierarchical database that stores low-level settings for the Microsoft Windows operating system and for applications that opt to use the registry. As registry editing involves altering core system configurations, it is crucial to proceed with caution and understand the potential risks involved. Incorrect modifications to the registry can lead to system instability or malfunction.
Before attempting any changes to the Windows Registry, it is strongly recommended to back up your registry or create a system restore point. This precaution ensures that you have a way to revert your system to its previous state in case any issues arise after making modifications. A registry backup can be created directly from the Registry Editor itself, or a full system backup provides a more comprehensive safety net. Taking a moment to secure a backup can save significant trouble if something goes wrong during the process.
To begin the manual removal process using the Windows Registry Editor, you need to open the ‘Run’ dialog box. This can be done by pressing the Windows key + R simultaneously on your keyboard. Once the dialog box appears, type regedit.exe into the input field and press Enter or click ‘OK’. You may be prompted by User Account Control (UAC) to grant permission for the Registry Editor to make changes to your system; click ‘Yes’ to proceed and open the editor window.
Within the Registry Editor window, you will see a tree-like structure on the left pane representing the different keys and subkeys. You need to navigate to a specific location within this structure. A convenient way to do this is by copying the registry path and pasting it into the address bar at the top of the Registry Editor window. The primary path for controlling the “This PC” folder view is:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\MyComputer\NameSpace
Paste this path into the address bar and press Enter. This will take you directly to the NameSpace key under the specified path. The NameSpace key contains subkeys, each represented by a unique identifier enclosed in curly braces {}. These identifiers, known as GUIDs (Globally Unique Identifiers), correspond to the various folders and locations displayed under “This PC” in File Explorer.
Within the NameSpace key you navigated to, you need to locate a specific subkey associated with the 3D Objects folder. The GUID for the 3D Objects folder entry is {0DB7E03F-FC29-4DC6-9020-FF41B59E513A}. Scroll through the list of subkeys under NameSpace until you find this particular identifier. Each subkey represents an item displayed in the “This PC” view.
Once you have located the {0DB7E03F-FC29-4DC6-9020-FF41B59E513A} subkey, the next step is to remove it. Right-click on the {0DB7E03F-FC29-4DC6-9020-FF41B59E513A} entry in the left pane. From the context menu that appears, select the Delete option. A confirmation dialog box will pop up asking if you are sure you want to permanently delete this key and all its subkeys. Confirm your action by clicking ‘Yes’. This action removes the registration of the 3D Objects folder from this particular registry location, effectively hiding it from the standard 32-bit view of File Explorer.
It is important to note that modern Windows 10 installations are predominantly 64-bit. On 64-bit systems, Windows maintains separate registry views for 32-bit and 64-bit applications for compatibility purposes. The previous step addresses the standard view, but for complete removal and to ensure the entry does not appear in contexts used by 32-bit components or legacy views, it is often necessary to perform the same modification in the 32-bit view of the registry, which is accessible via the Wow6432Node key.
Therefore, if you are running Windows 10 64-bit, you must also navigate to a second registry path. Open the ‘Run’ dialog box again (Windows key + R), type regedit.exe, and press Enter. Confirm the UAC prompt if it appears. This time, navigate to the following location:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Explorer\MyComputer\NameSpace
Paste this new path into the address bar at the top of the Registry Editor window and press Enter. This path leads you to the NameSpace key within the Wow6432Node branch, which is where registry entries for 32-bit applications running on a 64-bit system are often stored or mirrored. Similar to the previous location, this NameSpace key contains subkeys corresponding to various folder locations in File Explorer.
Within the NameSpace key under the Wow6432Node path, you will again find a list of GUID subkeys. You need to locate the same specific identifier associated with the 3D Objects folder: {0DB7E03F-FC29-4DC6-9020-FF41B59E513A}. Scroll through the list in the left pane to find this entry. It is crucial to ensure you select the correct key to avoid unintended consequences.
Once you have successfully located the {0DB7E03F-FC29-4DC6-9020-FF41B59E513A} subkey under Wow6432Node\...\NameSpace, you need to delete it using the same method as before. Right-click on the {0DB7E03F-FC29-4DC6-9020-FF41B59E513A} entry in the left pane. From the context menu, select Delete. A confirmation dialog box will appear asking if you are sure you want to delete the key. Click ‘Yes’ to proceed and remove this second registry entry.
Deleting these two registry keys (the one under HKEY_LOCAL_MACHINE\SOFTWARE\... and the one under HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\... on 64-bit systems) effectively unregisters the 3D Objects folder as a shell location within the “This PC” view of File Explorer.

After successfully deleting these registry entries, you can close the Registry Editor. The change should take effect immediately or after restarting File Explorer. To restart File Explorer, you can open Task Manager (Ctrl + Shift + Esc), find “Windows Explorer” in the list of processes, right-click on it, and select “Restart”. Alternatively, logging out and logging back in, or simply restarting your computer, will also apply the changes. Upon reopening File Explorer and navigating to “This PC”, you will find that the “3D objects” entry is no longer listed under the “Folders” section. This provides a cleaner, more streamlined look for users who do not utilize this feature.
While the manual registry editing method is effective, it does involve navigating potentially complex system settings and carries inherent risks if not performed carefully. For users who are not comfortable with editing the registry directly or who prefer a simpler approach, alternative methods exist. Several third-party utilities designed for customizing and tweaking Windows settings provide a user-friendly interface to perform common modifications, including the removal of specific default folders from File Explorer.
One such example is the Ultimate Windows Tweaker tool, which is designed to offer a wide range of customization options for Windows 10 through a simple graphical interface. Tools like this often include a dedicated option or checkbox specifically for removing the 3D Objects folder from “This PC”. Using such a tool typically involves downloading and running the application, navigating to the relevant customization section (often related to File Explorer or UI tweaks), and clicking a single button or checking a box. This automated approach abstracts the complexities and risks of manual registry editing, making it a more accessible option for many users. However, when using third-party tools, it’s important to download them from trusted sources and understand their functions.
The inclusion of the 3D Objects folder by default reflects Microsoft’s strategic focus on integrating 3D content creation and consumption into the Windows platform. With the development of applications like Paint 3D and the promotion of Mixed Reality technologies, Microsoft aimed to make 3D accessible to a broader audience. Providing a dedicated, easily accessible folder in File Explorer served as a logical step to support this initiative, offering a default save location and quick access point for 3D projects. This aligns with Microsoft’s history of continuously evolving Windows to incorporate new technologies and user capabilities, striving to make the operating system a central hub for various digital activities.
However, the rapid adoption of 3D content creation by average users did not materialize as widely as perhaps anticipated. While professionals and enthusiasts utilize these tools, many general users interact with their computers primarily for tasks like document creation, web browsing, media consumption, and photo management. For these users, the 3D Objects folder serves no practical purpose and merely occupies space in a prominent navigation area. The option to remove it caters to the demand for a more minimalist and personalized computing environment, allowing users to tailor File Explorer to their specific workflow and needs, free from elements they consider irrelevant clutter.
The 3D Objects folder is not the only default entry in “This PC” that users might wish to customize. Windows 10 also prominently displays user-specific folders like Documents, Downloads, Music, Pictures, and Videos under the “Folders” heading. While these are generally more useful for the average user than the 3D Objects folder, some users still prefer to remove them from this view, perhaps preferring to access them only via the Quick Access pane or through the user profile folder. The methods for removing these other default folders are similar in principle, often involving modifying different GUID entries within the same or related NameSpace registry keys. Understanding how to customize these views empowers users to create a truly personalized and efficient File Explorer experience.
Customizing File Explorer by removing entries like the 3D Objects folder is a common practice among Windows power users seeking to optimize their interface. Whether achieved through manual registry edits or automated tweaking tools, the goal is a cleaner, more functional environment. The ability to modify these default elements underscores the flexibility of the Windows operating system, allowing it to be adapted to a wide range of user preferences and technical requirements. For those who value a streamlined workspace, removing the unwanted 3D Objects folder is a simple yet effective step towards achieving that goal.
