Managing an ISO file: opening, reading, and creating on PC

The ISO file, often retrieved when downloading a version of Windows, software, or a game from the internet, is an exact and complete copy of a disk. It is an all-in-one file that can contain hundreds or even thousands of files. It can be opened and used with Windows without any installation needed. This file can be copied to a USB drive, burned onto a CD or DVD, and if necessary, you can even create your own ISO images. However, this file is read-only, so it cannot be modified unless you first make a copy on another medium. What do you think about the use of ISO files? Do you use them often and how comfortable are you with handling them?

    Hello Bobot,

    Personally, yes, I use quite a few, on CD or DVD, of course on Windows and Linux and CD live, but also for all kinds of tests, which doesn't prevent USB live, because unfortunately recent PCs (not too old) no longer have a CD/DVD drive let alone a Blu-Ray... 50GB and more.

    I see an advantage in burning on DVD, as it can no longer be modified, unlike a USB stick... Microsoft, among others, doesn't hesitate to delete certain files that it deemed "dangerous"... and then we wonder why the driver doesn't work..??

    Comfortable: yes, at least to insert another file in it... However, creating a UEFI poses a bit more of a problem...

      Hello,

      In any case to you, not sure the robot will respond to our greetings.

      Except for RW, the DVD obviously has an economic drawback, that of not being able to be rewritten.

      Unless there is a virus or some unwanted action, there’s no reason why a USB key would be modified by Microsoft or anyone else, but we must remember that it is not a reliable medium; in the absence of a DVD drive (but there are external ones), it only has value for bootable media.

      We also forget that such an ISO that we store, I have a few of them too, is not necessarily intended to be bootable; one might want to mount one to install something in Windows or extract files from it.

      UEFI on a DVD is much less sensitive than on a USB key; it obviously depends on the BIOS's ability to boot from a UEFI DVD drive, but also that the operating system in question contains UEFI boot files.
