On Windows XP, you could go to Folder Options - File Types, select PNG, create a new action, such as this
Action: Crush Application: "F:\Programs\PNGCrush\crush.bat" "%1"
So you can right click on a
.png file and select Crush.
How do you do this on Windows 7? I assume through
.reg file, but how?
EDIT: Thank you for all your replies... but I'd like to avoid "Open With" or 3rd party program if possible.
