I think all its tell you is that when they created the shapefile from whatever source database it was in, it shorted the field "stroke-Width" to "stroke-wid". It would do this because shapefile attribute names are limited to 10 characters. So if the person that sent you the file says something like "In the "stroke-width" field...." and you say "I don't have a "stroke-width" field just a "stroke-wid" field"... that confusion is averted. I doubt that it is necessary to use that file with the rest of the files that make up the shapefile. You could probably just not use that file and the shapefile would work fine. Its just there for information purposes.
