Backup Files
EAGLE creates backup data of schematic, board, and library files. They will
be saved with modified file extensions:
.brd becomes .b#1, .sch becomes .s#1, and .lbr becomes .l#1.
There can be a maximum number of 9 backup files.
It is also possible to have EAGLE files saved in a certain time-interval. In
this case the files get the extension b##, s## or l##. The files can be used
again after renaming them with the original file extension.
All settings concerning backups can be done in the Options/Backup menu
of the Control Panel.
Create EAGLE Projects
Lets create a new project first. After starting the program, first • the +
character of the Projects path, then • the + character of the entries examples
and tutorial in the tree view. The contents of the tutorial directory appears.
• tutorial with the right mouse button. Select the option New Project in the
popup menu. Name the new project MyProject, for example and hit the Enter
key. This way you are creating a subdirectory of tutorial that is named
MyProject. This directory should contain all data files that belong to your
project. Of course you may define additional subdirectories.
To define the path where your project directories will be stored, click
⇒Options/Directories and enter it in the Projects field.
A right mouse click on the project entry and you can open new schematics,
layouts and libraries. Each project directory contains a file named eagle.epf
which stores project-specific settings, window positions etc.
