In my virtual machine folder directory, there is a directory named Windows, which still cannot be deleted using the RM command. It prompts that it is occupied, but it is an empty folder. When I share this directory on Windows, it displays as messy code. After I delete it from Windows and refresh, it automatically appears again. What kind of folder is this? Why can't it be deleted? This problem has been bothering me for a long time. Shortly after I try some commands to force deletion, it will reappear.
