Converting bunch of .rar files to Iso or any other smaller size format

[Tru_Snoop]

Hi guys;

I have 1.92GB of .rar files (about 31 rar files), and one is SFV and other R30 file in them,also. These files are "Half-Life2" files. I want to burn them, but can't on one cd. Is there anyway to make them smaller. Can I convert them all to Iso, bin, or Img file? Can I collapse these files so it becomes one big file and then I can convert. I have extracted these files and I am able to play game. I can burn game directory files but they are more than 3GB. Can I convert these directory folders of half life to iso, img, or bin files? I have tried WinIso, but doesn't help..

thanks
