Binaries with "fs" SD card support NEEDED!!!

Next problem.... with my initial upload i followed a tutorial on the espruino main site.

There it said to flash using this line;

$ /path/to/esptool/esptool.py --port /dev/ttyUSB0 --baud 115200 \
  write_flash --flash_freq 40m --flash_mode qio --flash_size 8m \
  0x0000 "boot_v1.85.bin" 0x1000 espruino_esp8266_user1.bin \
  0x7C000 esp_init_data_default.bin 0x7E000 blank.bin

however there is no user2.bin in this line. So how do i figure out what location i must flash it to?
