Introduction to ISO
An ISO image is an archive containing an entire collection of data present in the CD/DVD and has a file extension .iso e.g. Microsoft Office 2007.iso. Such files can be extracted; burned to CD/DVD; mounted on virtual ROM and even transferred or mounted on flash drives.
Do I need to create ISO?
Unlike CD/DVD which can be copied to the hard disks, some important copyrighted discs such as printer, antivirus, premium software packages, games, operating systems etc may not allow copying of its contents. If at all, the contents get copied, some files may become redundant. On the other hand, CD/DVD gets damaged due to constant usage or exposure to moisture and ultimately become unreadable. Be cautious not to mount such disc into the CD/DVD ROM as it can result in permanent damage. Finally, if you are using a very old hardware such as printer. There is a high chance of not finding another CD in the market or even a local technician after a system failure. In such cases, creating a back up in the form of an ISO becomes vital.

Pros and Cons
- Once your iso is created, it will protect your programs from malware and offer some level of security.
- Any malware present in it will not be able to spread and serve as a temporary quarantine file. The malware will be triggered only by user intervention
- The iso file can be burnt to CD directly for use in future if the original CD gets damaged or lost.
- ISO files need to be extracted with 7zip, WinZip, winRar etc so, it is a must to have at least one of those programs with you.
- ISO files offer some level of security but this doesn’t mean you can be totally sure. Make a copy of it in cloud storage or external hard drive. Some malware’s may be specifically written to attack archives. That’s the reason for additional copy
