How to Open a DAT file
Before anything let me just tell you what a DAT file actually is.
A DAT file is a nonspecific data file. It contains raw data that may be opened or referenced by a specific application. While some DAT files can be opened directly, most contain program data that is referenced to the program when it is running. Therefore, most DAT files are not meant to be opened manually. Plus many a times you can’t even open a .dat file.
