Patricia, "Depending on the date you bought the Male Pak, some of these folders may not be present on your computer." As quoted, some folders/files may not exist on your machine. Most were created by the original installer. The folder/files in the face library were created by an update (which is no longer applicable). The new installer Ryan has been contacting everyone who purchased the MalePak about, is a replacement for the original installer... The original one is safe to delete along with the files it created once you have downloaded the replacement. -Rob
