title: Findstr -- exclude a file type -- search only ascii
body: <p>I want to run a FINDSTR dos command in a way beyond what it is easily found in "findstr /?".  How would I run findstr so that it only searches ascii files.  (I am not sure if that is possible. My gut feeling is that it is not possible)  Additionally, how would I run this command line so that it would exclude some file times.  For example, what if I wanted to exclude .psd files</p>
