[Mortimer452]

Using a pattern or just as single filename, anything in the excluded files box causes the task to fail.

Message:
`System.Management.Automation.CommandNotFoundException: The term 'ex' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
