Using layers overview

Layers are like transparent sheets of acetate stacked on top of each other. When you create a new Flash movie, it contains one layer. You can add more layers to organize the artwork, animation, and other elements in your movie. You can draw and edit objects on one layer without affecting objects on another layer. Where there is nothing on a layer, you can see through it to the layers below.

The number of layers you can create is limited only by your computer's memory, and layers do not increase the file size of your published movie. You can hide layers, lock layers, or display layer contents as outlines. You can also change the order of layers.

In addition, you can use special guide layers to make drawing and editing easier, and mask layers to help you create sophisticated effects.

It's a good idea to use separate layers for sound files, actions, frame labels, and frame comments. This helps you find these items quickly when you need to edit them.
