Files that have a .dat extension contain data for an application or document on your computer system. DAT files cannot be normally opened and information extracted like other file types, since they are connected to specific programs on your computer. Information from DAT files can be extracted using Microsoft Word and from there, you can attempt to figure out what program the DAT file is associated with.
