The zip filesystem is read only, and I'm not sure there is a filesystem with write support available for the Altera HAL. You may have to move to ucLinux or eCos, or try to port a filesystem code you can find on the net (such as fatfs (http://code.google.com/p/minini/wiki/fatfs)) to Nios.

You can also use alt_write_flash_block to write, but it will be written as a bsoc, not as a filesystem entry. You would need to read it back with alt_read_flash_block.
