title: Chrome Extension App Open exe on File System
body: <p>I am struggling to find an answer to this question so I was hoping somebody experienced with Chrome apps and extensions could point me in the right direction.</p>
  
  <p>I've not written any extensions or apps before so I am just trying to get to grips with it.</p>
  
  <p>I am currently developing a POS system for my company and it's basically done and ready to go. On completion of a transaction I need to open the Till drawer connected via USB to the clients machine. All the machines will be owned by us therefore I can manually add the extension and app to the machine as well as the exe that opens the till. </p>
  
  <p>I have found some sample apps that I am currently working on and I am successfully passing message between my extension and app. The next stage is to then open the exe via the app.</p>
  
  <p>Can someone please clarify if opening an exe via an app is possible and if so presumably I would do this by adding filesystem permissions</p>
  
  <pre><code>"permissions": [
      "fileSystem"
    ],
  </code></pre>
  
  <p>Then do I need to use the read methods of the api?</p>
  
  <p>Similarly if it is possible to open an exe, do I access this using</p>
  
  <p>file///C:/path/to/exe</p>
  
  <p>If it is not possible to open an exe, I could potentially install xampp on the customer machine and have a php script execute the exe file. In this instance I would need to post data from the app to the PHP page.</p>
  
  <p>I believe I could use Jquerys post function to do this.</p>
  
  <p>Any help/alternative solutions or resources you are aware that could help me solve the issue would be most appreciated. </p>
