@Bill Greiman - Is SdFat not case sensitive to file and directory names and if so is there something a setting in the config file that I might have missed or can change?
@KurtE - I ran some tests on LittleFS using lfs_stat() and found that it is case sensitive. If the filename does not match case wise then it returns -2. If they do match it returns 0.
This not a problem. I was just curious. Could not find it in the LittleFS docs
