When an artifact exports from MFT the name looks like: so_916dffd7-19fc-406e-9fac-12b46fe79d0f.xml, this makes it hard to determine which files to pick then deploying a transfer and its associated files, so the ExportTransfer operation will rename the file to the name you provided when you create the artifact for example: ABCTransfer.xml. These files are renamed back (to id.xml for example: so_916dffd7-19fc-406e-9fac-12b46fe79d0f.xml) during the build stepof the transfer that it contains. This name will then be the one that is checked into SCM if you add additional steps to the workflow.
The purpose of this operation is to simplify getting MFT artifacts into an SCM, and typically this operation will be used in a workflow specifically built to populate SCM, rather than in the build workflow.
