Hello,
Not sure it's a right place for asking this question ... if not ... please advice where should I look for help.

I want to use Emacs as and editor and shell. On Windows 7 I installed cygwin , X11 and emacs. In terminal I added to /etc/profile file these lines:

XWin -multiwindow 2> /dev/null&
export DISPLAY=:0.0
sleep 1
emacs 2> /dev/null&

I created a shortcut that execute this command: C:\rhcygwin64\bin\mintty.exe - Now every time I start that shortcut it starts emacs. No problem. My goal is: associate some file types like .txt , .csv and etc with emacs in order when I start foo.txt it'll open in emacs. When I tried to do it 'Set Associtation' control it accepts only file name and it does not take '-'. Hence when I try to open foo.txt it does not work. I tried to create a shortcut to mintty.exe but it didn't work either. Could someone help me to create association in order to start to mintty.exe but rather mintty.exe - ? Thanks in advance

This question isn't even about Cygwin, much less Linux. MSDN has good information on how file associations work.

Thanks for the link. Unfortunately it did not help me. It looks that in my case 'simple' association a file type with a program would not work because it involves a few additional conditions.
Well I am stuck.
The only option that I see is every time I need to open a file just save it somewhere and then open from inside the Emacs.
Not convenient... But I don"t see other option
Thanks
