DXAdvanced now comes with a Media FIFO function (external media overwrite function), starting with R2 (release 2). This function ensures that the external medium (CF card) always retains the latest data when files are saved to it automatically. When the CF card is full, the oldest files are deleted to make room for the newest files. The media FIFO function allows you to use the DX continuously for long periods of time without having to change the CF card. It is also useful in cases where you want to save the latest data to the CF card as a backup, such as when automatically transferring DX data to an FTP server.
