CoordFiles (.PTS files) are automatically associated with the Copan program. That is, in Windows Explorer, a .PTS file is labelled as a Copan CoordFile and will open inside Copan if it is opened. (To open a file, double-click its icon or right-click it then choose Open.)
If that file association is not happening, you can reinstall Copan (version 08.04 or later), ensuring that the Associate coordinate files (*.pts) with Copan task is checked.
