4 A First Look at EAGLE
The HOME variable must not point to the root directory of a drive!
Backup
When files are saved, EAGLE creates backup copies of the previous files. The
maximum backup level field allows you to enter the maximum number of
backup copies (default: 9). Backup files have different file extensions,
enumerated sequentially. Schematic files receive the ending s#x, board files
b#x, and library files l#x. x can run from 1 to 9. The file with x = 1 is the
newest one.
The automatic backup function also permits the backup to be scheduled. The
time-interval can be between 1 and 60 minutes (default: 5 minutes). The
backup files have the endings b##, s## and l## respectively.
All these backup files can be further processed in EAGLE if they are renamed
and given the usual file endings (brd, sch, lbr).
If the option to Automatically save project file is chosen, your project is
automatically saved when you close the current project or leave the program.
User Interface
The User Interface dialog allows the appearance of the editor windows for
the layout, schematic diagram and library to be adjusted to your preferences.
You can also access this menu from the Editor windows.
In the Controls box you specify which objects are to be displayed in the editor
window. If you deactivate all the Controls, only the command line will remain
for entry. This maximizes the free area available for the drawing.
