SetFolderType
Set Windows Explorer folder types using Desktop.ini files
This program adds a right-click context menu to Windows Explorer that allows you to set the folder type for an entire folder tree by creating (or editing existing) desktop.ini files in each folder.
Why set folder types using Desktop.ini files?
Background Information
Windows supports setting the folder type to one of General items, Documents, Pictures, Music, or Videos with the appropriate entry in a hidden, system file named desktop.ini. This has the advantage of making the folder type setting permanent to the folder itself. You can reset your profile, create a new user, or reset Windows, and the folder types will be remembered and displayed with whatever view you have chosen for that folder type.
Note: To globallly set your preferred folder type views, please see WinSetView
However, there is a catch. Explorer only provides this functionality on drives that mount as Local Disk (aka “fixed disk”) and are formatted NTFS. Therefore, this tool will work on all internal drives that are formatted NTFS, but it will only work on some USB drives. For example, SanDisk USB SSD drives mount as type Local Disk, so they will work with this tool if the drive is formatted to NTFS.
Partial Fix for Windows 11
For Windows 11, this tool provides a partial fix for some broken funtionality in the Windows 11 Explorer. Specifically, the feature Also apply this template to all subfolders is completely broken in Windows 11 (assuming you have not patched Windows 11 to run the Windows 10 Explorer). Here’s a video demonstrating the issue.
The fix is partial because, as noted above, it only applies to drives of type Local Disk that are formatted NTFS. For such drives, SetFolderType will give you back the ability to set the folder type for an entire folder tree.
Permanent folder type setting for both Windows 10 and Windows 11
For Windows 10 (or Windows 10 Explorer on Windows 11), the feature Also apply this template to all subfolders works fine, but there is still a scenario wher you may want this tool.
As noted in the Background section above, setting the folder type via desktop.ini files makes the folder type setting permanent because it’s part of the folder, instead of just a registry setting.
How to Download and Install
Note: Some antivirus software may falsely detect the download as a virus. This can happen any time you download a new executable and may require extra steps to whitelist the file.
- Download the zip file using the link above.
- Extract SetFolderType.exe.
- Right-click SetFolderType.exe, select Properties, check Unblock, and click OK.
- Move SetFolderType.exe to the folder of your choice (you need to keep this file). Keep the Language.ini file with the Exe if your language is not English.
- Double-click SetFolderType.exe to open the Install/Remove dialog and click Yes to install.
- If you skipped step 3, then, in the SmartScreen window, click More info and then Run anyway.
- Click OK when the Done message box appears.
Note: Sometimes the Done message pops up behind another open window. If that happens, you should see the SetFolderType icon on the taskbar, where you can click to bring that dialog to the front. Alternatively, you can minimize the window(s) that are on top of the dialog.
Note: If you move SetFolderType.exe after installing, the context menu entries will do nothing because the exe path will be incorrect. To fix that issue, just run the install again (as descibed in Step 5 above).
Command line Installation and Removal
If you wish to install or remove the tool via the command line, usse these commands:
SetFolderType /install
SetFolderType /remove
About the context menu
The context menu item is created with registry entries only and simply provides submenus entries for each folder type. When one of those items are selected, SetFolderType.exe is run with the appropriate arguments to set the selected folder type for the selected folder tree.
This program does NOT create a context menu handler. That is, there is no code that runs when you right-click a folder. Code only runs when you actually select an action (i.e. select a folder type that you want applied). SetFolderType will add no overhead to your context menu, other than the insignificant impact of one more context menu item.
How to Use
Right-click any folder and you should see the SetFolderType context menu:
Select the folder type you want applied to the folder. This will create (or edit any existing) desktop.ini file in the selected folder and ALL of its subfolders, all the way down the tree.
Patience!
Although SetFolderType is very fast at populating all the subfolders with desktop.ini files, it’s up to Explorer to update the view. Explorer does that in the background as it notices the addition (or change) of the desktop.ini files. How long it will take is variable. It depends on the speed of the computer, what other processes are running, how many folders are affected, and so forth. But it can often take 30 seconds or so for all the folder views to update. So, before you jump onto GitHub and post an issue, relax, do something else for a minute and then go back and check your folders. You should see that Explorer did its thing and updated the view.
The view won’t change if you’re looking at it!
Explorer will not update the folder’s view until the folder is closed. However, having an open folder only stops the view update for that particular folder level. The subfolder’s views will update even if you have the parent folder open.
The target folder must be on a Local Disk that’s formatted NTFS
If the target folder is not both a Local Disk and NTFS, an error message, indicating which criteria are met (or not), will be displayed. Here’s all three error possibilities:
Remove Desktop.ini Files
If you select (None) from the context menu, SetFolderType will remove all desktop.ini files from the entire selected folder tree. This will work on all drive types and files systems. The check for Local Disk and NTFS is skipped for this action.
It’s Multilingual!
Here’s an example of SetFolderType installed for German (de-DE):
SetFolderType will detect your Windows language and use it, as long as it can find the Shell32.dll.mui file for your current language. If that file is missing, you will see this error:
This error often occurs if you just installed a new language. Windows sometimes takes a long time to populate the language folder with the MUI files. Sometimes you just have to wait a few minutes. Other times, the MUI files don’t show up until you run Windows Update. For some reason, just running Windows Update to check and/or get the latest updates forces the language installation to complete.
If you get that error but are OK with English, you may click OK and continue to install the tool with English context menu entries. If the missing MUI file is added later, you can simply double-click SetFolderType.exe again to install it in the correct language. The install always removes any of its previous context menu entries before creating new ones.
If the MUI file is found, the Install/Remove dialog will appear in the correct language:
Note for Vietnamese: On Windows 10, the file C:\Windows\System32\vi-VN\Shell32.dll.mui may be missing. Without this file, SetFolderType will not be able to provide a Vietnamese display. One way to fix this issue is to copy the missing file from a Windows 11 computer that has the Vietnamese language installed.
