If you use the command prompt method to create a folder in the Lenovo notebook Windows system, such problems will occur if the file name ends with more than 2 dots, and the file name displayed in the system will automatically hide a dot in the file name. Add a dot after the folder name "x." and use Run to enter the address to open it (the address bar and IE browser still cannot open it). This method can be used to open folder names such as dots or dots, but please note The name of the folder must be added to the original name with a period.

Deletion method: Go to the directory where the folder is located in the command prompt and enter "rd x..\\" Press Enter to delete.
