title: What to do with "The input line is too long" error message?
body: <p>I am trying to use os.system() to call another program that takes an input and an output file. The command I use is ~250 characters due to the long folder names. </p>
  
  <p>When I try to call the command, I'm getting an error: <code>The input line is too long</code>.</p>
  
  <p>I'm guessing there's a <code>255 character limit</code> (its built using a C system call, but I couldn't find the limitations on that either).</p>
  
  <p>I tried changing the directory with <code>os.chdir()</code> to reduce the folder trail lengths, but when I try using <code>os.system()</code> with <code>"..\folder\filename"</code> it apparently can't handle relative path names. Is there any way to get around this limit or get it to recognize relative paths?</p>
