One of my acquaintances, who has just got his first personal computer, has a weird new hobby – buying and copying CDs and DVDs (music, applications, movies) to his laptop’s hard drive. His reason is that he wants to put his collection all in one place, and he has plenty of storage space to spare. But being a first time computer user, he used a bit of a strange way of doing it. He copied everything inside the discs and pasted them onto the hard drive.
The first time I met the concept of a disk image was in the late 90′s when I unsuccessfully tried to play a computer game without the CD. Back in those days, many software makers required that the installation/data CD’s were to be present in the tray before the application could run. If you used many applications and each one of them required several CD’s, repeatedly inserting and changing those CD’s could become very annoying. It would be much better if users transformed those CD’s into disk images and mount them using virtual drives.
