ESP32 Forum

Hello friends, a question I have always read that the SD.h library does not support long names, so after formatting an sd as fat32 I tried creating a file of 80 characters like:
111111.........(80 characters).txt
and it has worked without problems, recording data, reading, listing files... etc...

So it seems that the information of that library is not updated?

Thanks for your opinions.

It does support up to 250-ish bytes long, which is consistent with Fat long names.

Ok, thanks for the clarification
