These files are located in the “PallCartStyles”, directory, every ballooning style of the environment has a dedicated PRS file usually called with the same name as the style. These .PRS are just a copy of PallCart.prs with the settings defined by the user for that specific style and are called with the name of the style. Within this same directory it is contained a file called "CONFIG.PRS". This file has declared inside the correspondence between the name of the style, visible through the interface for the styles management, and the name of the file it is referred to. Its functionality is however accessible through the the ballooning styles interface, so that the user has no reason to edit this file manually.
