'DLL Hell' is a term, know too well for comfort between Microsoft Windows developers. 'DLL Hell' causes grief and despair when two (2) separate and essentially incompatible versions of a DLL file with the same name are installed with one over-writing the other. This can cause the first program whose DLL got over-written to stop functioning.
Enter .local that redirects windows where to search for a specific dll. If a file application.exe.local exists, Windows will first look in that application's directory for the DLL file. If .local is a directory / folder, Windows will search in that directory instead of the application directory.
