Take the 2-minute tour ×  Is there a way to open files with
unknown extensions, or no extension, in a text editor by
default?  I'm mostly interested in doing this on Windows 7, but
it would be nice to know how in Mac/Linux too.  share|improve

at 15:48  2 Answers 2  Microsoft has a knowledge base article
for just this situation:  KB236014 - "INFO: Shell Extensions for
File Names with No File Extension"   For example, to associate a
program (for example, Notepad.exe) to open all files with no
extension, use the following registry keys:     @="<path to
notepad.exe> %1"  share|improve this answer Sorry it took me a
while to get back to you on this... I tried saving it as a .reg
and executing it but that didn't seem to help. Is there a
special trick to it? Thanks! This sounds perfect –  Jeff Jul 28

as Windows does. Neverthel
