Staying organized when you're working on compositions is critical, especially in an application such as this, where you're going to bring in so many different types of assets from movies to still images to audio to logos, I mean it can really, really get crazy. So what I want to talk about here is how to use folders. As you see over here in our project panel we have a little folder icon and we can click on it to create a new folder and it's already highlighted so we can just type something. So I'll go ahead and just type assets. Then I hit Return to accept that. Now as you see when I have assets selected I can click on the new folder icon again and it will create a new leaf in this tree here. So I can say, movies for example and once again I can click on assets, click on a new folder and I can say something like, stills. So as long as I go back to the main folder I can always create children of that folder and I can collapse it by clicking or twirling the arrow. If I want to create a brand new branch I can click away from it like so and now I have a new folder, and once again I can do the same thing, click on that folder and add new folders within that folder. Or if this folder is selected click on it again and I keep creating a new branch and I collapse that one and collapse that one. I can also get rid of these guys by clicking on it like so and clicking on the garbage can and I'll get a warning that tells me it has other things contained in it. Another cool thing about After Effects when you're dealing with folders is that when you import files you don't have to import you know one at a time. I can click on this folder here that has these files in it and click import folder. It brings the whole folder in with the name and images that were contained within it. So, you can organize your file structure elsewhere and then bring that folder in, in one fell swoop. If I want to put this vice folder in the assets folder, I click and I drag and I drop it right on in there and now it's a part of this assets folder. And if I want to take it out, just click and drag it away and it becomes a part of its own branch again. So folders are a very important, in my opinion assets when working with After Effects because you can keep yourself organized and never have to worry about where a particular asset is. Once again by the way if for example I imported this folder and on my hard drive I relocated this real folder here, After Effects will ask for the location of the folder because it won't know that you've moved it. It will know that you move it, but not where. So keep that in mind, try to find one place on your computer that you're going to work with and try to stay in that region because you can accidentally miss the connection between your assets by moving them around on your computer.
