Currently, I need to adjust some files used to automatically create tables.  The files are ordinary text files, but they do have extensions that are not .txt.  I am looking for certain words, and sometimes the "find" command will find those words in files, and sometimes it misses them.  Any ideas on what I might be doing wrong?  Also, could anyone point me to a good online resource for windows command prompt batch files and windows scripting in general?  Usually, the ones I find are for network administrators, covering stuff that I do not even have access to, let alone a professional need. 

One thing.  I cannot install any new software on my computer.  It's not allowed where I work.  So cygwin and the like is out of the question.
