    yes

    it depends on if your system has a hard disk?

    and I'm guessing it doesn't

    I think this way is first step for you.

    in basic way, you have to access devices via address.

    if you want file-system, you have to create file-system some how.

    there is several way like Linux/uC-OSII...

    you can create file-system by your self(it's difficult)

    so, if you are new to NiosII.

    you can read and write data via UART(RS-232C) , JTAG, SPI, I2C...
