function Get-DbaXESessionTargetFile {
    <#
        .SYNOPSIS
            Get a file system object from the Extended Events Session Target Files.
 
        .DESCRIPTION
            Get a file system object from the Extended Events Session Target Files.
     
            Note: this performs a Get-ChildItem on remote servers if the specified target SQL Server is remote.
 
        .PARAMETER SqlInstance
            The target SQL Server
 
        .PARAMETER SqlCredential
            Login to SQL instnace with alternative credentials
 
        .PARAMETER Session
            Only return files from a specific session. Options for this parameter are auto-populated from the server.
 
        .PARAMETER Target
            Only return files from a specific target.
 
        .PARAMETER InputObject
            Allows results from piping in Get-DbaXESessionTarget.
 
        .PARAMETER EnableException
            By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
            This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
            Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.
