how to open gerber or gbr file extension

[Ridgy]

Does any one know how to open a gerber file with a .gdr extension? I have googled for a long time and the only programs I can find cost around $100 but as I am a student I can't afford that. One website said that XnView could open these but I can't work out how. I need it to open some files in electronics. Any help would be appreciated. thnx

Sorry the .gdr extension is sposed to be .gbr extension. in too much of a rush.

Please have a look at FAQ "Does XnView support graphic format .xyz?". Looking at the list of formats supported by XnView there is GBR support, but this means GIMP brush.
