assuming that somehow this activity was legal, since sending CD images over the net is not. The only legal way i can think of is your friend doesnt have a CD burner and wants u to back up his CDs. However this turial is for educational purposes only and i cannot be held liable for any illegal activities comming from its contents.
1. What you have are a bunch of .bin and .cue files. The .bin ones should be about 600mb each and teh .que a few kb. The .bin's are the CD images and the .que's are the writing instructions.
2. Open up some sort of CD burning software, such as Nero, or Alcohol 120% (highly recommended), and burn the images. However you must not make them data disks, but burn the actual images. I dont know how to do it in nero, but in alcohol 120% u just go to image burning wizard and browse to find where the CD images are stored. Each .bin is for 1 CD. I highly recommend Alcohol 120%, search for it on google and find a trial version to download.
