Specific file that can be opened

Hello I have a problem with my Arduino board its a clone I work on Windows and I can no longer upload its me but its message: ser_open(): can't open device ".\COM3": The sp�cifi� file cannot be found.
I'm going to check my devices and the arduino board has a code 10 problem. I've looked at all the forums and I can't find it.

Can I suggest that either you translate the topic title to English or that you translate your post to French and ask a moderator to move the topic to the French section of the forum
