Ok, so I have been reading and googling this for a while now and I can't understand what is going wrong. I am trying to create a .int file extension in my registry so that I can add the ShellNew key to it and thus it should allow me to do the simple right click > new > file method of file creation. So I went to HKEY_CLASSES_ROOT and I created a key called .int.
I then created a key called intfile with a default icon and set its (Default) string to "Localization File". Then in my .int key I set the (Default) intfile and created Content Type which i set to plain/text. Then I created a new key called ShellNew and in that key I set FileName to the path in WINDOWS/ShellNew where my default .int file was. However, when I right click and go to new it does not show New Localization File. Am I missing a registry entry somewhere? Any help will be greatly appreciated, I can't figure out why this isn't working as I have added ShellNew to many keys before and had it always worked flawlessly. This is my first time creating a completely new file extension but I have read other file extensions that exist and can't see why it isn't working. Ty again in advance.
Edit: Clarification of what I have set up exactly.
intfile:
(Default) REG_SZ "Localization File"
intfile>shell>open>command:
(Default) REG_SZ "C:\Program Files\Notepad++\notepad++.exe"
.int:
(Default) REG_SZ "intfile"
ContentType REG_SZ "plain/text"
Percieved Type REG_SZ "text"
.int>ShellNew:
(Default) REG_SZ "null"
FileName REG_SZ "C:\WINDOWS\ShellNew\New Int.int"
