Getting content of a local file without uploading [duplicate]

Question

I'm writing an offline webapp that allows user to select local file, modify it and than saves a copy also locally. Is it possible without any server (I can upload a file and return base64 of it, but it's not much of a offline)? App needs to work only on Google Chrome, so maybe I should look here?

Answer 1

The HTML5 File API might prove usefull
