emoncms-export.sh includes the phpfiwa folder and the settings.ini file in the compressed *.tar.gz backup files.
However, emoncms-import.sh does not re-import the phpfiwa folder nor the settings.ini this file. They remain as orphaned files in the import folder.
These files, which may contain feeds and user-specific data, should be imported into their destination folders (or removed after import if they are obsolete).
