Micro-SD cards can store gigabytes of data in a very small space. They are used with cell phones, USB modems and other small devices. Normally, you would need a micro-SD card adapter to transfer files from your card to your computer, but you can also transfer files without an adapter using a cell phone with a micro-SD card slot.
