Localstorage as you think is not a DataBase or even the File System, it's just some plain JSON files that store tiny bits of data in key: value pairs.

If you have worked with JSON before this will be very easy to grasp the Idea behind it.

Below is an example of setting and retrieving values from Local-storage:

locastorage.setItem('KEY',JSON.stringify('VALUE'));
// KEY is kind of like the variable name and the VALUE is the actual Data

JSON.parse(locastorage.getItem('KEY'));
// You use the KEY to access the value

// Using JSON methods stringify and parse just to be on the safer side.

HTML5 Localstorage is not for files.

Have a look at Mozilla's documentation here: https://developer.mozilla.org/en-US/docs/Web/API/Storage/LocalStorage

Instead it's for key/value pairs.

// Save data to the current local store
localStorage.setItem("username", "John");

// Access some stored data
alert( "username = " + localStorage.getItem("username"));

To start a download, you may want to look at a question like Download File Using Javascript/jQuery
