3 years ago The SDFat API is not same as ESP32 SD API - so it won't work by just changing the SD reference
You need to virtualize SDFat to use same FS API as ESP32 SD . typicaly File of SDFat is not same File of ESP32

I am trying to make WiFi SD for 3D Printer on ESP32 using your ESPWebDAV library. For SD I use because I think it's faster.
If i connect (uncomment) your library, an error occurs during compilation.
I'm not very good at C. Can you tell me what i can do?
To make it easier to understand, I removed everything unnecessary from the program.

SdFat SD; File myFile;
void setup() {
if (!SD.begin(5, SD_SCK_MHZ(20))) { Serial.println("initialization failed!"); return; } Serial.println("initialization done.");
// open the file. myFile = SD.open("test.txt", O_RDONLY);
myFile.close(); } void loop() { // nothing happens after setup }
