For the Mac I'm using the apple widget PNGPong to shrink png files. It's using Optipng to shrink the png file which is dragged upon this widget. For windows I was thinking about creating something similar with an Air app.
Been reading about dropping a file upon an Air app, but for this to work the app would have to include the optipng.exe file. So the idea is: I drop the png file upon the Air app, this png file is then processed by the optipng.exe file with a line like 'optipng -o7 draggedfile.png', this processed file is returned.
But is it possible at all to include exe files within an Air app?
