title: What file structure should one follow if a lot of files are to be downloaded in android app?
body: <p>I am working on an android app and using ionic framework to build it. The application requires a lot of media files to be downloaded on the phone. These files can be categorized as <em>images, videos or sounds</em>. Right now I am saving the with their file type concatenated with the file name </p>
  
  <p>eg. image-boy.png, sound-boy.png and so on</p>
  
  <p>Such that all the files are in the same directory. </p>
  
  <p>The average file size should be 0.2 Mb and the total number of files any user can download is around <strong>3500</strong>. </p>
  
  <p>Should I use a different <strong>file structure</strong> like saving different file types in different directories (which I think, is generally followed) ?
  What difference can it have on the <strong>performance</strong> of the app ?</p>
