title: Unity WriteAllBytes Web Player alternative
body: <p>I have an app that uses a sync function where all the content is saved locally from a server (CMS).</p>
  
  <p>On the server I have text, images and videos. The script is downloading all that info and then is saving the text in text files and images and videos as bytes. In the editor and on android is working well and my question is how I can use an alternative to <code>File.writeAllBytes</code> for the web player. I searched a lot for solutions but I didn't find any. How I can access the file system on local storage from the web player or how can I use the cache system for this?</p>
