INFO: Shell Extensions for File Names with No File Extension

This article was previously published under Q236014
Shell extensions for file names with no file extension can be registered under the following:
For example, to associate a program (for example, Notepad.exe) to open all files with no extension, use the following registry keys:
[HKEY_CLASSES_ROOT\.]@=""[HKEY_CLASSES_ROOT\.\shell][HKEY_CLASSES_ROOT\.\shell\open][HKEY_CLASSES_ROOT\.\shell\open\command]@="<path to notepad.exe> %1"				
Here is an alternative method:
[HKEY_CLASSES_ROOT\.]@="NoExtFile"[HKEY_CLASSES_ROOT\NoExtFile][HKEY_CLASSES_ROOT\NoExtFile\shell][HKEY_CLASSES_ROOT\NoExtFile\shell\open][HKEY_CLASSES_ROOT\NoExtFile\shell\open\command]@="<path to notepad.exe> %1"				
NOTE: "NoExtFile" is not a predefined name, and therefore it can be anything. Adding other shell extensions is similar to adding shell extensions for file names with extensions.
Please refer to the Platform SDK documentation on Shell Extensions for more information.
