How do I use a custom schema.ini file?

[Guest_imported]

In the Help for the TransferText action it says that I can use existing specifications or my own schema.ini file. I found a description of the layout for this file and have created my own but I'm unclear as to how to call this file in my TransferText argument.
DoCmd.TransferText acExportFixed, &quot;<what goes here?>&quot;, &quot;<table/query name>&quot;, &quot;<filename>&quot;, False, &quot;&quot;
