FTP from SD card connected in SPI mode

Hi, I would like to transfer file(s) from SD card to Windows PC via WIFI. SD card is connected in SPI Mode. (Note: Connecting SD Card via 1 or 4 bit MMC mode appears to be black magic) ESP32 will play the role of the simple FTP server. Which library to use and how to set up a sketch to make it work?
