The File Menu
This section covers the functions accessed through the File menu item.

Open
Open is used to bring a previously edited set of maps and settings from a file on a hard disk, CD-ROM, USB jump drive, SD card or any other storage device. When the laptop software is started, it automatically loads the maps and settings from the last file saved. To open a file, select File→Open:

Hydra Nemesis 2.7 map files have a “.hyd” extension in the Windows© operating environment. Older 2.6 files using the “.s26” extension can be imported using the “Import 2.6 Map File” option under the file menu.

Note: Older 2.1 and 2.5 Map Files using the “.s20” extension cannot be imported.



Save
The save option is used to save the current set of maps and settings in an existing file on any storage device. When the laptop software is started, it automatically loads the maps and settings from the last file saved. To save to a file, select File→Save, or press F2:

If the map has not been saved before, a dialog box will open asking you to save the file in a directory on your drive. If the map has been saved before, this function will overwrite the previous file.

Click on the Save button to save the file after you have selected the device, folder and name for the file. Otherwise, click the Cancel button to cancel the save.

Although it is possible to select an existing file to save to, doing so will overwrite the contents of the file so that the maps and settings that were previously stored there are lost. If you are careful to choose unique and meaningful file names and save often, you will be able to quickly undo unwanted changes and easily go back to previous maps and settings.


Save As
This option allows you to save a new file separate from the previous file you are currently editing. A dialog box will open asking you for a directory to save to. Click “Save” to save the file or “Cancel” to cancel.

Because the laptop software always starts with the maps and settings of the last file saved, it is often a good idea to save the maps and settings in the laptop software to a file before exiting. By doing so, the Hydra Nemesis 2.7 unit and the laptop software will contains the same maps and settings the next time the laptop software is started and no time will be wasted transferring the maps and settings from the system to the laptop.
