A method is provided to customize the appearance of the Cache cube icon in the system tray so different instances can be visually distinguished. When csystray.exe, the Cache/Ensemble cube program, starts, it will look for files named "up.ico" and "down.ico" in the \bin directory below the instance installation directory. If these .ico files are present, csystray.exe will load the icons and display them in place of the default blue and gray Cache/Ensemble cube icons.
XDATA is used for a whole host of ISC libraries to store things like Zen pages, BPL logic and DTL transformations.
