With File API it is possible load data from local files into the browser memory via Javascript. I'm accessing huge files (200MB and bigger) on a system that is low in available RAM (webapp on an mobile device). How can I use the W3C File API (or Cordovas File Api as a fallback) to partially load data (e.g. by specifying a byte range) from files?
