USMT - Move only file types that I specify

Question

All the documentation seems to indicate that the default user.xml file will only migrate specific file types (.doc, .xl*, etc.) However, I have created dummy files in c:\test with a file extension of *.abc and that file is being migrated as well.
I know that I can exclude certain file types, but what if I only want to move specific types and everything else is not migrated.  The documentation seems to indicate this is the default behavior, but it's not working that way.  Anybody know how
to NOT migrate file types unless I specifically state they should be migrated (regardless of location on the disk).
Thanks,
Chris

Hi,
If you want to exclude a file type from the migration, regardless of the other <include> or <exclude> rules, you can use the <unconditionalExclude> element. This element excludes objects globally across all components:

The following .xml file excludes all .mp3 files from migration:
<migration urlid="http://www.microsoft.com/migration/1.0/migxmlext/excludefiles">
<component context="System" type="Documents">
<displayName>Test</displayName>
<role role="Data">
<rules>
<unconditionalExclude>
<objectSet>
<script>MigXmlHelper.GenerateDrivePatterns ("* [*.mp3]", "Fixed")</script>
</objectSet>
</unconditionalExclude>
</rules>
</role>
</component>
</migration>
