------------------------------
    Resolution: Won't Fix

With the new features introduced in [XMLHttpRequest|https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest], this plugin is not needed any more. Migrating from this plugin to using the new features of [XMLHttpRequest|https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest], is explained in this [Cordova blog post|https://cordova.apache.org/blog/2017/10/18/from-filetransfer-to-xhr2.html].

> When starting a download we receive calls to updatePrrogress and corresponding javascript callback this many times, so CPU will get to almost 100% and UI will non or very slowly responsive.
> I just made a workaround in https://github.com/OliverZiegler/cordova-plugin-file-transfer.git on branch iOS_throttle where the updateProgress event will only be send to the javascript source every second.
> We didn't get this issue on Android.
