Hi,
I am successful using the T3.6 and internal Sd-card.

I can report a folder from a folder using File entry where the File Class has methods that provide name() and size() but not date.

I can get date/time by using:
card.init(SPI_QUARTER_SPEED, _csPin);
volume.init(card);
root.openRoot(volume);
root.ls(LS_R | LS_DATE | LS_SIZE);

I hope someone has:
received the card information as a string or series of strings as opposed to direct output to the Serial Monitor.
received the file/date/size from a folder as opposed to the entire card
sorted the directory according to date or alphabetic as opposed to random.

Otherwise it is modifying the SdFile.cpp.

thanks,

Richard
