InViewer is a very simple app for opening verious media files quick and easy on any Windows machine out there. Since you need many different programs to open media files like images audios and videos, now you only need one. The stock programs for these files are very heavy, slow and anything but smart. InViewer is weighs only about 300 KBs, is portable and has a smart user interface. It can handle nearly every common file format, and also for example GIF animations. These animations cause a big problem in Windows PCs, because there's no valuable viewer for them.
