\r\n\r\n1. Storage<\/strong>. In them, we can store a huge amount of information that can be transferred over the internet, for instance.\r\n2. Portability<\/strong>. Whenever you create ISO images of the discs that contain important information or information of our interest, they allow us to store said images on smaller devices (any extractable device that could be connected via USB, for instance,) where we will be able to transport them without needing to carry those annoying disc towers from one place to the other.\r\n3. Functionality<\/strong>. There are multiple occasions when we have information stored in discs (CD, DVD, Blu-ray) that we want to open in other devices, but these devices lack the respective units to play discs. This won\u2019t happen if we have said information on an ISO image and if we have USB ports or slots to transfer information to the new device (and also slots that read SD or microSD cards).\r\n\r\n\r\n\r\nMaybe one of the disadvantages of ISO images is that they do not compress the backed-up information<\/strong>. Instead, they preserve their original size.\r\n\r\nThis could be an inconvenience if, for instance, we wish to transfer an ISO image of a large size via email.\r\n\r\nEven so, there will always be other tools that allow us to achieve our goals, if that were the case, such as using the famous WinRAR, among others.\r\n
