Does esp8266 save old sketches?

then in the html handle, I have

        //       P r o g r a m   U p d a t e d
        strcat(html, "Program Updated");
        strcat(html, *ctdotd);
        strcat(html, __DATE__);
        strcat(html, *ctdotd);
        strcat(html, __TIME__);
        AddToTable();

        //      __FILE__
        strcat(html, "File");
        strcat(html, *ctdotd);
        strcat(html, __FILE__);
        strcat(html, *ctdotd);
        strcat(html, "name");
        AddToTable();
