Windows 11/10 comes with several useful features, and the ribbon menu of File Explorer is one of them, which helps users to carry out various tasks including Select, Cut-Copy-Paste, Share, etc. Among the included features, you will find an option called “New Item” in the Home tab of File Explorer’s ribbon.
This New Item option allows users to create a new file in a particular folder. If you use this option, there is no need to create the file in some other location and then move it to your desired folder. Using this option, you can create the file directly in any folder. It makes the task easier to perform. But it may be that you do not find your desired file type there. For example, you may have Photoshop installed on your PC, but you will not see any option to create a .psd file in the “New Item” section.
Add new file type in New Item of Explorer Ribbon menu
We have seen how to add new file type in the right-click context menu’s “New” option. It is even easier to do the same with the New Item of File Explorer’s ribbon. Before you begin, make sure you backup your Registry files. This trick has been tested on Windows 10 but works on Windows 11 too.
Now decide which file type you want to add. It could be a Photoshop .psd file extension or it could be any other one. If you want to create a new PSD file, the extension is .psd. Similarly, the XML file extension is .xml. This will work if you have the software that creates these file extensions installed on your computer.
Now open the Registry Editor on your computer. To do so, press Win + R, type regedit, and hit Enter.
Navigate to the following key: COMPUTER > HKEY_CLASSES_ROOT.
Here, you will find all the extensions you want. Find your desired extension. Right-click on the extension > select New > Key. Name it as ShellNew.
Select ShellNew key and create a new String Value on the right-hand side. To do so, right-click on the space > select New > String Value and name it as NullFile.
Now, create a demo file in the app. For example, in this case, you need to open Photoshop, create a new layer of your desired size, and save the template with any name ending in .psd.
Next, go to C:\Windows\ShellNew and paste the .psd file in that folder. In case you do not find the ShellNew folder, create it manually.
Finally, in the Registry Editor go to COMPUTER > HKEY_CLASSES_ROOT > file_extension > ShellNew. Right-click on the right-hand side > select New > String Value and name it as FileName. Double-click on the String Value and enter the file path that you pasted in the ShellNew folder in the prior step.

Now, you can find the option to create a PSD file in New Item of Windows 10 File Explorer.

Sometimes, you may not need to create a demo file to get it done. However, if your File Explorer does not show the option, you need to create a demo file as described above.
Hope it works for you.
