why there is .DAT extension file in the OS X Lion

[Patchers]

In the System/Library/Linguistic Data/ folder there are files with .dat extension. At present they are set to open with mpeg application. It’s not right. What should be the file association? I am using Lion on MacBook pro with Intel core 2 duo 2.2 GHz

.dat files have no detailed application that will open them. There is no standard format for the data within the .dat file. Many applications will maintain a .dat file, although that doesn't make them the accurate program.

To open those .dat files, you would require a program that can really read that specific format.I don’t have any idea which program will open .dat file

I guess what I actually require to be acquainted with is how to disassociate these particular .dat files with mpeg program stream. I am having trouble with the dictionary not opening in Pages. I think this might be the reason. It looks like I set all .dat files to open with mpeg program. I have to find out which program will open .dat files.

.dat was extension for digital audio tape files (keep in mind Dat recorders) it is also the much loved and well recognized extension for Winmail.dat files
