This program is for transferring all contents of SD card to any flash drive like pen drive. After importing this program, you will see 3 FATFileSystem libraries, one in main folder, one in SDFileSystem folder and one in USBHost folder. Delete two libraries, which are in SDFileSystem folder and USBHost folder. But don't delete the FATFileSystem library, which are in main folder.
Dependencies: FATFileSystem SDFileSystem TextLCD USBHost mbed
