Viewing Mangas and GCs -

You can unzip/unrar all the files to your local folders by using Winzip/Winrar or other zipping tools, then view the images by using image viewing/editing tools.

Or you can use CDisplay  or similar tools to view Mangas/CGs files directly without unzipping the files.

H-Games with image files like .cue, .bin or .iso -

Uncompress the downloaded games using Winrar/Winzip or any zipping tools that can.

The best way is to use Daemon Tools to mount the image file as a Virtual Drive and install the game(s) to your PC. Or use a CD burning tool and burn the image to a disk then install the game afterward.
