IMG format is used to represent the disc images that can be mounted as a disk drive (like an external hard drive) or an optical disc (such as CDs or DVDs).
In order to be able to access these files, users will need to find a compatible software solution that supports the format.
These applications will allow users to mount their IMG files to virtual drives and to explore their contents.
Some of these utilities can also be used to generate custom IMG files that will store the files selected by the user.
