Is it possible to open many files and affect all of them with one or two changes?
For instance, I have a folder of 2000+ iPhone icons. I would like to make them all black and white and lighten the brightness. I calculate that it would take me over 7 hours to do this, if I did it one at a time and it took me 10 seconds each. I'm not willing to invest that much time in such a tedious task.
Is there any way I can accomplish this goal speedily?
Thanks for the help.
