The file name, directory name or volume label syntax of the U disk is incorrect, and the folder overlay cannot be created. What should I do?

Hello, there are many reasons for this situation, so I won't say much here. I also searched other possibilities. But the result of my analysis of your problem now is: in the first case, there may be a folder named "New Folder" in your USB flash drive, but it is hidden. You can show all hidden files and then delete folders with the same name. The second case: the format of your USB flash drive is inconsistent with that of the computer system. Solution: You can copy the files in the U disk and format them. Just choose the default format. I hope I can help you. Thank you.
