visual studio 2010 not showing all files in a directory

I have approx. 105+ web fi开发者_开发知识库les (.aspx, .css, .html, etc...) files in a folder. I've created a 2010 web project, but for some reason, not all the files show up. It stops at the letter p, every file after that (q* - z*) is not showing in the project. I created a new project, but still they are not showing up.

Could there be a bug in VS 2010 that doesn't show files after some point?
