An SD card is a flash based memory card used in equipment such as cameras and computers. Its smaller cousin, the MicroSD card, functions just like an SD device and even fits into an SD card slot, with the appropriate adaptor. In order to record data onto the MicroSD card you must have a computer with an SD card slot, or at least an external SD card reader connected.
Plug the USB data cable running from the SD card reader into one of the USB ports on your computer. If the computer already has an SD card slot you can skip this step.
Side the MicroSD card into the SD card adaptor. This adaptor enlarges the MicroSD card, allowing it to fit into a standard sized SD card slot.
Insert the SD card adaptor into the SD card slot, then close out the AutoPlay window that loads onto the screen.
Click "Start," "Computer" and double-click the removable device icon to load a window onto the screen that displays all the data currently stored on the card.
Click-and-drag data from the computer into the open window to record the file information to the MicroSD card. Once the file transfer is complete (which is shown by a progress bar that appears) you can eject the MicroSD card from the computer.
