An annoying fact when designing in Photoshop is that you quickly accumulate a multitude of layers. Even with Photoshop’s advancements in the layers arena, it gets out of hand quickly. The best thing you can do is delete unused layers. A quick way to delete multiple layers in Adobe Photoshop is to Shift+click or Command+Click the layers you don’t want, then click on the Layer Palette Trash icon. Don’t forget that you can save a Layer Comp before you delete the layers, that way you can quickly return them if necessary.
