The default drive for a virtual CD is defined the first time that CD is inserted in a virtual drive. This drive is used by various mechanisms when the virtual CD is inserted automatically. Virtual CDs can generally be inserted in any virtual CD drive, but some programs will not function properly unless their CD is in a particular drive. Virtual CD lets you see which drive is the default drive (it is usually the drive from which the program in question was installed) by displaying it in the Quick Start utility menu and in the Explorer extension.
