Bree's were also labelled as XML Document. Open one in a text editor and see what it looks like. Should look something like this
<?xml version="1.0" encoding="UTF-8"?>
<!-- -->
<!-- BDF v3.2.0 Image and backup definition file for Macrium Reflect v8.0 -->
<!-- -->
<!-- This file is a template XML to enable a Reflect backup or Image to be initiated from VB Script or an -->
<!-- MSDOS batch file. -->
<!-- Simply modify this file if required and pass the file name as a parameter to reflect.exe. -->
<backup_definition version="2.0" reflect="v8.0.5994">
<!-- backup or image file properties -->
<properties>
Mine were also listed as xml document in explorer.
Once after an update, Macrium "lost" my definitions. They were all in Reflect folder where they should be just they weren't listed in Macrium.
As stated you should be able to use the add button, in Macrium, navigate to the definition and add.
