On the PS3, DLC pkg files are packages that contain additional game content, such as new levels, characters, or game modes. These files are downloaded from the PlayStation Store and stored on your console's hard drive.
If you're a PS3 owner who's been enthusiastically downloading DLC (Downloadable Content) for your favorite games, you might have encountered a frustrating issue: your PS3's DLC pkg files are full. This can prevent you from downloading and installing new DLC, which can be especially problematic if you're in the middle of a game and can't progress without the additional content.
