try making an ajax request to retrieve the file. Example with jQuery:

$.get('url to your local file')
.done(()=>{ alert('file exists'); })
.fail(()=>{alert('file cannot be retrieved');});

I get the popup "file cannot be retrieved" – ThePat02 Mar 28 '18 at 12:27
if the file actually exists, make sure the url is correct and you run your script and access the file from the same domain. e.g. http://localhost/ – Eriks Klotins Mar 28 '18 at 12:36
As said, the file is opened locally, so there is no domain. It is offline. – ThePat02 Mar 28 '18 at 12:37
