A memo on how to create ISO files from CD/DVD discs in Windows to enable mounting. In conclusion, we use ImgBurn, a convenient free software, to create ISO files from CDs and discs.
With ISO files, you can virtually mount CDs even without physical CDs or when CDs are not mounted. For example, a common use case is games. Some games require Disc 1 and Disc 2, but even for such games, if you create ISO files and mount them virtually, you can run them on other PCs, your friend’s PC, or inside virtual machines.
