What is Shadowing?
Shadowing refers to overriding a resource that is located in a Pleo application (usually in the internal DataFlash) with one that is separate from the application (typically on an SD Card). To shadow a resource, a file with same name or ID is created with the proper extension (based on resource type). When the Life OS resource manager looks up a resource, it will look to the SD Card first. If a file of the proper name is found, that will be used instead of what is internal. All resources can be shadowed, including sounds, motions, commands and scripts.
