Hi guys and congratulations with the new BiaB2013!But...It seems I have a problem,or not?since the BiaB2012 I have a lot of .dmg files,which are growing and the map BiaB gets a lot of Gb's, I wonder -do I have to keep them all,once they've been installed(talking about .dmg files),or I can just delete them?Or I should burn them to disk and after it,delete them?How about the overall performance-nothing will go wrong?Any advice?
