Using ISO files is a very popular way of distributing a large amount of files over the internet. A lot of software packages are available online as ISO files you can download. ISO files can also be used to easily back up files, such as photos, videos, or programs you have downloaded, in an easy-to-access form on a hard drive or a CD/DVD.

We found a free, portable tool, called Folder2ISO, that allows you to create ISO files from folders in Windows. Download Folder2ISO from

Folder2ISO is a front end interface for the Mkisofs program. Mkisofs is used to write file systems, such as iso9660, that are used to create CDROMs. By default, the Hide Mkisofs check box is selected so you don’t see the status of Mkisofs running in the background. If you want to see that status, select the Hide Mkisofs check box so there is no check mark in the box. A command window displays showing the percentage complete of the Mkisofs process. The command window automatically closes when the Mkisofs process completes.
