# Open

The open function is activated either by selecting the Open item of the File Menu or by pressing the open button from the Main Window. Figure 1 shows the open tool button.

The open function in HUGIN is like the open function in most other applications: It opens a saved HUGIN network. It can open files of both HKB format (compiled HUGIN network format) and NET format (standard network description format).

If the file is a password protected HKB file, a password dialog opens, in which the user can specify the password. If the password is incorrect, opening the file will fail.
