compilation error: pure virtual function "fs::FileImpl::path" has no overrider

Hello, compiling the example (test.cpp) I got error:

*** [.pio/build/esp32dev/src/main.cpp.o] Error 1

Could you please help what is the solution?

The environment:

platformio platform = espressif32 board = esp32dev framework = arduino ide: eclipse

@lszlfrng take a look here: https://github.com/peterus/ESP-FTP-Server-Lib/pull/13/files

you can just fix it on your site if you copy that new line into the FTPFilesystem.h in your libdeps/--platform--/ESP-FTP-Server-Lib/ folder

After the modification, the source code has been compiled without error.
