File extension gbr is related to files in standard Gerber Format used in PCB industry.

Gerber File is a file format used by printed circuit board manufacturing machines to layout electrical connections such as traces, vias, and pads (the component footprints on the PCB). In addition, the file contains information for drilling, and milling the completed circuit board.

The latest version (2014) of this format is covered under Extended Gerber, or RS-274X specification replacing the previously used RS-274-D. But the file extensions are still the same.
