What are DAT videos?
You may meet or use DAT file format in the possible ways such as: for VCD video files, generic data files and the Winmail.dat files used in email, etc. DAT files are generally used to reference data files, which contain data in ASCII format and are normally comma delimited.
The file name extension .dat is used for VCD media files. A DAT file is actually saved in MPEG-1 or MPEG-2 format, containing the actual video data that is played from the VCD. The important thing is that the DAT file for video CDs can be played on CD players and the users do not have to open the DAT file manually.
