  • Note that the ISO is a file that is similar to a compressed, but that it is not the same, but rather an exact copy of it and its relationships within a given file system found on the CD.
  • If the files are transferred to another file system, such as the hard disk, NTFS or FAT format, it is possible that the relationships between the files will change to be able to adapt to the system of the new disk and therefore it will no longer work. be executable. can only copy an ISO file to hard drive as ISO, without unpacking or trying to change its properties.
  • Whenever possible, it is recommended not to download the ISOs with download managers. If you have a manager that opens when you start a download, it’s a good idea to disable it before you start. This is because the managers split the file into several parts, which are then joined when the download is finished, but the program can tell if the parts occupy entire files or only a part of them, which can cause small parts to be lost. of information, thus leaving the ISO almost useless.
