I've created a layer package and would like to be able to add its contense to a map in ArcMap. I have tried opening it using the Add Data button but the layer file does not appear where I have saved it. However I am able to open the layer through my computer's file directory but that creates a new map which would basically force me to start over.
Basically what I want to know is how do I open this layer package to be used in an existing map?
