i found some error when i use SD library and i don't know how to fix it i use esp32

this is a error text

@nowzenith Would you please post all #include directive statements for your sketch that encountered this error? I'll consider a workaround.

@nowzenith Since mySD.h defines the File class as global, it conflicts with FS.h provided by the ESP32 Arduino core as standard.

The main reason is that the SD_Extension class depends on mySD.h. Does the SD_Extension library have compatible with the ESP32 Arduino core? In my view, if the sketch uses the filesystem with FS.h provided by the ESP32 Arduino core, including SD_Extension.h will cause a compilation error always in the sketch. It's not just about AutoConnect.

The filesystem of the ESP32 Arduino core is separated from the physical media, and the physical IO layer as a lower layer provides an API that can be accessed in the same procedure regardless of whether it is EEPROM or SD. https://github.com/espressif/arduino-esp32/tree/master/libraries/SD

SD_Extension should be ported to follow this structure.

Thank you so much
