As we all know, the greatest benefits of the image file format are security, stability, and high compression. Therefore, many collectable files are made into ISO or other image file formats for preservation and distribution. Instead of burning an image file as a CD/DVD as before in order to view the files inside, you can always use a file archiver like 7-Zip to direct extract them out (which can be time-consuming), but a better way to do that is use a virtual drive.
