Guides help to control the size and location of the slices you will make in Photoshop. They are optional but often set the stage for a successful artwork set. Organization using folders is key to making sure the art layers are easily hidden when needed.
This feature works the same in all recent versions of Adobe Photoshop: CS5, CS6, and Creative Cloud (CC).
Folders can be created in the Layers Panel to organize layers. They can then be expanded and collapsed to make the Layers Panel more manageable.
