Why Doesn't XP Pro Show Size, Time and Date Mod of a Created File?

[W. eWatson]

I created a folder, and wrote a file to it. When I look at what files 
are in it, they are correct. However, The Size, Type, and Date Mod are 
not shown. Why am I missing those columns? I'm writing files with a 
suffix of dat, which seem only to match up with video CD movie.
