How to create a file with no file extension using Windows?
My extrasensory perception (ESP) is telling me that you are trying to create it using Windows Notepad.
That is (I.e.):
C:\My Documents> notepad myheader
And Windows Notepad creates a file called "myheader.txt
".
You can do
C:\My Documents> notepad myheader.
(Note the dot after "myheader".)
This creates a file without a file extension on Windows and with Windows Notepad.
