If you're a premier member of lynda.com training library, you've got access to the exercise files used in this course. The exercise files are really easy to use, you'll notice that I've sorted them into folders according to chapters. in order to use them, you just open the projects. And if I open up the 04 math folder, you'll see that each folder is sorted into numbered project files. So we have 401 CS6, 401 aep.
So this is the CC version, this is the CS6 version. And if I go to List View, you'll be able to see them listed 1, 2, 3, 4, 5, 6, 7, 8. So photo one relates to section one of chapter four. Photo two relates to section two of chapter four, and so on and so forth. So if I open up this one, let's have a look at what happens here. It tells me, this project must be converted from version 11. This was the CS 6 version, so obviously it's an earlier version than the version of After Effects I'm using.
That's nothing to worry about, we just click OK. Now, sometimes when you move folders, particularly the source files folder, you may get and After Effects warning, three files are missing since you last saved the project. This doesn't mean the files are actually missing, it may mean that After Effects just can't find them on your system because it will have a different file path. It's not a problem. All you need to do is click OK, and then go over to the Project panel and in this text field at the top, type in the word Missing, and all the missing files will be brought forward represented by these color bars.
All you need to do is double-click on one of them, and then find it. And it will be in the Exercise Files folder, inside source files. And inside there, we should see wideshot PNG. And all I need to do is relink one of them, and it will relink all of the other ones in that relative path, and then you can carry on working. So, it's not a problem if there are missing files. You can just relink them like that. Now, each project, if I open another project here.
I'm not going to save that. And I'm just going to show you one of the other projects. Let's have a look at this one. one of the first projects, we get the same warning about it being a CS6 project, and then we go straight into the project. And you'll see here within the project, I have numbered compositions. So each chapter will have numbered compositions for the particular section that you'll be going through. And often they have start and end versions of the compositions also. So you can check your results with the end version.
