A method for quickly displaying files in an external storage device through vehicle-mounted multimedia equipment comprises the following steps: reading file structure from the external storage device to create a corresponding FAT mapping table; creating a corresponding page structure; ranking the contents of the FAT mapping table according to a ranking algorithm; loading contents to be displayed to at least one page structure according to the created page data structure based on the size of the contents to the displayed; and carrying out page switching and loading according to user's operation. The method can effectively improve the utilization rate of CPU idle resources and space of a machine, can not only compensate defects of slow operation reaction and display of a vehicle-mounted multimedia equipment scheme under a low-rate USB/SD communication mode, but also reduce repeated ranking processes of the system during USB/SD operation process under condition of ensuring larger memory space, and accordingly, the user's operation for the browser is more smooth so as to improve user experience.
