Over time the Windows system directory can become cluttered-up with unused DLL's (program libraries) which waste disk space and slow the system down. The more files there are in your system directory the longer the system takes to locate a file there.

Clean System Directory application will scan your system looking for all references to DLL files in your Windows system directory.

Those DLL files in the system directory that have no programs calling on them can be moved out of the system directory, saving disk space and improving system performance.
