The Save As dialog will appear. Type a name for the file.
The TopoGrafix Data File format (.loc) has been replaced by the GPS Exchange format (GPX). If you open a .loc file, you will
be prompted to save it in GPX format.
GPS Exchange format (GPX) is an open, documented standard for exchanging GPS data. Over 55 other GPS and mapping programs support
GPX. If you use a program which does not yet read and write GPX files, please contact the program's author and let them know that GPS
data exchange is important to you.
