As we mentioned in our previous tutorial, there are times when you will want to make a copy of your project files to a new directory, and re-generate code there.

There are lots of reasons why you might want to do that, but the most compelling reason is that you want to leave the original project completely intact, so there is no possibility of it getting changed.  That way, you are sure that you can go back to something that you know is still working, if your new approach doesn't work out.

In this tutorial, we'll make a copy of the project we worked on in the previous tutorial, in which we added several variables and controls to our layout, regenerated code, and then used Beyond Compare 3 to copy our "real I/O" code to the newly regenerated files.

We'll use more powerful directory comparison and multi-file copy capabilities of Beyond Compare 3 (or BC3 for short) to speed up the process of "cloning" our existing project.
