Early in development, the data file was only ever XML so there's some
legacy code such that if Tellico opens an XML file, it will continue
to be saved as an XML file, regardless of the file extension.

Once it's loaded, whether it's XML or not shouldn't make anything
slower, I don't think.

Try File -> Export -> Export to Zip, which should force the file type.
Just be sure not to include the images!

If you had to do it manually, Tellico expects the file name inside the
zip file to be named tellico.xml, so if you rename your file to
tellico.xml, then use the command:
  zip newdata.tc tellico.xml

You should then be able to open newdata.tc with Tellico.
