The commands of the menu File serve for manipulation with files and for program termination.
This command uploads data for the network adjustment from a file. The program can work with two file types:
Groma: The format of the GROMA system
CTU: Text format used at CTU Prague
This command serves for saving the network in a file. If the network has already been named (if already saved or if uploaded from a file), the program will save the network under the old name without any further questions; but if the name hasn't been entered yet, the program will ask for the name before the saving.
This command serves to save the network in a file. Unlike the previous command, it will always ask for the file name.
