title: Prevent other software from opening my files?
body: <p>How can I lock a file in Windows and only give permission to a certain piece of software to open it?</p>
  
  <p>I have developed some scripts for special hardware. Another piece of software (written by a big company) reads my scripts and executes them on the device. I'm going to distribute the scripts, and the customers shouldn't see the contents of the scripts, or be able to copy them. I can't encrypt the scripts -  if I encrypt them, the software can't read them (it doesn't have the option of reading an encrypted file).</p>
