The Overwolf simple-io-plugin

A very useful plugin that we’ve developed is the simple-io-plugin. This plugin allows your app to perform different filesystem I/O operations.

It is very useful for:

  1. Reading a game’s log file(s) and even “streaming” the log file, line-by-line, to your app.
  2. Creating your own persistent file on the local disk.
