I need to call to a program, gifsicle.exe. This is a command line program for manipulating gif image files. It works only in the directory where it is present . It outputs to a file but doesn't allow me to use the mode batch. I would like to try to extend the capabilities of this program by (1) calling it it from a root directory; (2) batch a number of directories in one call; (3) create an output file as a log of all my calls.
I am new to programming and would like a step-by-step instruction as to how I can complete this.
