You can open any Help project file, whether you used the Help Project Editor to create it or not.
To open a Help project file
1.1.From the File menu, choose Open Help Project.
The Open Help Project dialog box appears.
2.2.If the file is on a different drive, select the drive you want from the Drives box.
If the drive to which you want to change does not appear in the Drives box, it may be a network drive to which you are not connected. Connect to the drive, and then use this dialog box option.
3.3.In the Directories box, double-click the directory you want.
Or press the UP ARROW or DOWN ARROW key to select the directory, and then press ENTER.
The current directory initially is the same directory as the currently selected file in the Help Project Editor window.
4.4.In the File Name box, double-click the name of the file you want to open.
Or select the file, and then choose OK. (The default extension is .HPJ, so initially only files of that type will appear in the list box.)
Or type the filename in the box, and then choose OK. You can enter a full path in this box, including drive and directories.
