Explanation

The .nfo (info) file extension is a plain-text or styled-text information file, commonly used by software distribution groups to describe a release. It is NOT a graphics format. The other extensions are all legitimate image formats: .tga (Targa - used in game development and video), .bmp (Windows Bitmap - uncompressed raster image), and .psd (Adobe Photoshop Document - layered image file). In computer forensics, knowing file extensions vs. actual file signatures (headers) is critical, as files can be renamed to hide their true type.
