Please paste the output from the example sketch and front the SD listfiles sketch.
Hi Steve, thank you for your reply.
The output of the IniFile sketch is just:
Ini file /net.ini does not exist
The output of the listfiles sketch is:
NET.INI 1207
done!
The output of the CardInfo sketch is:
Initializing SD card...Wiring is correct and a card is present.
Card type: SDHC
Clusters: 1952581
Blocks x Cluster: 32
Total Blocks: 62482592
Volume type is: FAT32
Volume size (Kb): 31241296
Volume size (Mb): 30509
Volume size (Gb): 29.79
Files found on the card (name, date and size in bytes):
NET.INI 2018-07-15 14:44:18 1207
My IniFileExample sketch is:
#include <SD.h>
#include <SPI.h>
#include <IPAddress.h>
#include <IniFile.h>

I hope this can help you to find out the problem,

That's not a problem I've encountered before. Sorry I can't help.
Hi, I installed the iniFile library 1.0.3 from library manager but the IniFile Example Sketch doesn't find the filo on the SD card. I tested the SD with the sd/listfiles example and it works fine.
Any suggestion is appreciated.
