Dynamic link Library, abbreviated: DLL, is a program module that can be shared by other applications, encapsulating programs or resources that can be shared. It is very similar to an executable file, except that the dynamic link library contains executable code that cannot be executed separately, but is called directly or indirectly by the application.
Part of the software is uninstalled, and the installed dynamic link library files are not deleted from the system. As users install/uninstall more and more programs, there may be redundant dynamic link libraries on the hard disk. Therefore, the Windows Optimizer master provides users with the ability to clean up redundant dynamic-link libraries (DLLs).
Enter the redundant DLL cleanup for System cleanup maintenance, tick the hard disk partitions to be analyzed, click the Analyze button, and Windows Optimizer will automatically analyze whether the dynamic link library on the hard disk is useful and list the results of the analysis. The list of results from left to right is the dynamic link library file name, version, dynamic link library description, size, last modified time, and directory. Users can learn more about the dynamic-link library in the list.
After the check is complete, the user can expand the items in the analysis results list. The Windows Optimizer master describes the dynamic link library name, version, description, size, last modified time, location, status, and so on.
When a redundant dynamic link library is deleted, the Windows Optimizer master automatically backs up the dynamic link library, and if there are problems after deletion, the user can click the "Restore" button to enter the backup and Recovery manager with the Windows Optimizer master and choose to restore the dynamic link library.
