I use Proteus 8 and when I use the old gerber format (RS274X) it spits out *.GBR files. The fabhouse (PCBWay) wants all the files to have different extensions (.GBL for bottom layer, .GBO for silkscreen overlay etc...) Having the rename all of the files gets tiring quite fast so I wrote a batch script to automate the process...
I always check gerber files before production just to make sure everything is fine (Free Online 3D gerber viewer:
http://mayhewlabs.com/webGerber/) and guess what, the batch file works great!
If you want to use it yourself you'll probably have to modify a couple of things but the script is so simple that pretty much anyone could do it! (Also don't hold me responsible if anything goes wrong
)
I linked in below to script and a screenshot of what it does. enjoy!
