The Hidden "What If"

But wait--there's more (cue the Ginsu knives)! Pull up the slider from the bottom of the screen. What do you see? It reveals your "what if" scenario, should you take the highlighted difference and apply it to your original text file!

Merging Directories

If we can do this with individual files, what about directories (UNIX-speak for folders)? Of course! Here are two folders with a few differences between the two:

Let's see how we can compare the directories quickly. Do what you did before--drag and drop each directory into its own well, and click Compare.

After initialization, you see a different view of the folders' contents:

You can filter out what is identical from one to the other, or show which files are different from one to the other (the Added/Deleted checkbox). You can choose to combine, remove or unmark files using the drop-down menu. I will chose to combine the files by highlighting them, and save all of the files with a new name:

Let's see if that worked:

We Rock!

Go ahead and get all those files merged and then put them in new merged directories--then go home to a great dinner. First, check your email. It's your boss again, asking if you make certain "things" happen when people launch Safari or other applications. You think, "Is he nuts?" He might be, but you can make applications sit up and beg--with Property List Editor. Tune in next time for more fun with Xcode tools.
