// Save 
var source = new FlowDocument();
var range = new TextRange(source.ContentStart, source.ContentEnd);
using (var stream = File.Create("output.pak"))
{
    range.Save(stream, DataFormats.XamlPackage);
}
 
 

 
// Load
using(var stream = File.OpenRead("output.pak"))
{
    var target = new FlowDocument();
    var range = new TextRange(target.ContentStart, target.ContentEnd);
    range.Load(stream, DataFormats.XamlPackage);
