.GBS File Extension

The name of the GBS file is derived from the name of your PCB. Therefore, if your PCB is called "MyProject," the file will be called MyProject.gbs.

Gerber format files, like GBS, are stored in RS-274X format and act similar to .PDF files. They're an exported version of the PCB layout and are meant to be viewed and referenced but not edited. They're utilized by PCB manufacturing machines to designate electrical connections between components with pads and tracks.

NOTE: The GBS format was originally developed by Gerber Systems but is now maintained by Ucamco.

In the GBS application, there are a variety of GBS files located in different directories. One example of a GBS file is target.gbs. This file is used to associate file extensions with builders, such as compilers and linkers, for a specific target. It is located in the GBS_SYSGEN_PATH/​target directory. Another example is steps.gbs, which is located in the GBS_SYS_PATH directory. This file defines the conditions and order for generating or auditing SubSystems.

NOTE: Other examples of GBS files include audit.gbs, export.gbs, flags.gbs, incs.gbs, owners.gbs, sca.gbs, scope.gbs, switch.gbs, sys.gbs, system.gbs, and tool.gbs.

You can open a GBS file in OtterUI Editor (Windows) by opening the OtterUI project (GGP file) the GBS file is associated with. Typically, GGP files are stored in the C:/​Program Files (x86)/​Aonyx Software/​OtterUI Editor directory.
