Files that contain the .sol file extension are files that contain settings and user data that is saved for the Macromedia Flash Player. The SOL file format is only used by Flash versions 6 and later. SOL files are very similar to the cookie files that are created by many different websites on the Internet. Because of this, these files are commonly referred to as Flash cookies.
SOL files contain local shared objects. These objects are shared across multiple Flash player sessions to save a user's settings and information, allowing the information to be used across multiple Flash player sessions.
