Converting a folder to an ISO file is important and practical for a number of reasons, including reliable data backup, ease of distribution and rapid transfer of files, and creating installation discs for certain software. ISO files are suitable for archiving and sharing large amounts of data because they preserve the integrity of the folder structure and provide easy access to the content. This format allows for quick loading on virtual machines or disk emulation, helping the user to make optimal use of their data without the need for a physical disk. Folder2ISO is a free, portable standalone software for creating ISO files from folders.
