A: In Windows, many applications are not a complete executable file, they are split into relatively independent dynamic link libraries, which are DLL files, placed in the system. When we execute a program, the corresponding DLL file is invoked. An application can have multiple DLL files, and a DLL file may be shared by several applications, such that a DLL file is called a shared DLL file. DLL files are generally stored in the C:\Windows\System directory. You cannot delete a folder if it is empty. If deleted, there is a problem with operating system operation.
