Connection files (.hco)
Each connection
that you define in a ZIETrans project is represented by a connection
file. The connection (.hco) files are stored in the project_name/Connections
folder,
where project_name is the name you gave
the project when you created it. The default connection, which is
created using the connection values that you specify in the New ZIETrans
project wizard, is stored in main.hco.
