Thank you Calin!

I tested my programm and my file jpg (sd 4go) with IDE Arduino 1.8.5 on another M5Stack .
It works very well.
The first M5stack doesn't work propely.
I hope the M5stack store will change it.

and also
I tested with a 32mo

I use a SD 4mo FAT32

I use Visual Studio too.
i have just tested your programm and i still have the problem.
I think it's a hardware problem.
I'm waiting for another device
Thank you.

i have install PlatformIO and load my projet:
