How to Implement Custom Verbs for Folders through Desktop.ini
In Windows 7 and later, you can add verbs to a folder by using Desktop.ini. For more information about Desktop.ini files, see How to Customize Folders with Desktop.ini.
Note
Desktop.ini files should always be marked System + Hidden so they won't be displayed to users.
To add custom verbs for folders through a Desktop.ini file, perform the following steps.
Instructions
Step 1:
Create a folder that is marked Read-only or System.
Step 2:
Create a Desktop.ini file that includes a [.ShellClassInfo] DirectoryClass=Folder ProgID.
Step 3:
In the registry, create HKEY_CLASSES_ROOT\Folder ProgID with a value of CanUseForDirectory. The CanUseForDirectory value avoids the misuse of ProgIDs that are set not to participate in implementing custom verbs for folders through Desktop.ini.
Step 4:
Add verbs under the Folder ProgID subkey, for example:
HKEY_CLASSES_ROOT
CustomFolderType
Shell
MyVerb
command
(Default) = %SystemRoot%\system32\notepad.exe %1\desktop.ini
Remarks
Note
These verbs can be the default verbs, in which case double-clicking the folder activates the verb.
