VTF Viewer is a tool for viewing Source Engine format texture files. Program allows you to view whole folder full of VTF's and other image files as a collection of thumbnails. You can view all mip levels of VTF files as well as read their flags. You can also save them as bitmaps or jpeg images. This is only a first initial beta release, later we are planning to add a .gcf packages support so you don't have to extract textures to view them as you need now.
