Hi everyone

I've past near an hour ready post about SD.exists method issues encountered by other but nothing similar to mine.
I think all is said in the main title :
I'm using CardInfo.ino example.
I just add a simple test : SD.exists( "filename.txt" )

The method root.ls found and list down all file including "filename.txt"
but, SD.exists method said it's not existing.

I don't understand why.
I have try some variation name, capital later, 8.3 format... nothing help.
Impossible to test existing file.

I think I missing something just below my nose but I'm see nothing.
Can you help me please ?
