ISO FILE

An ISO file, often called an ISO image, is in fact an "image" of an entire CD or DVD. The entire contents of a disc can be perfectly represented in a single ISO file.

You can think of an ISO file like a box that holds all the parts to something that needs built - like a child's toy you might buy that requires assembly. The box that the toy pieces come in does you no good as an actual toy but the contents inside of it, once taken out and put together, become what you're actually wanting to use.

An ISO file is the same way. The file itself is no good unless it can be opened, assembled, and used. The most common way to make use of an ISO file is to burn the ISO file to a CD or DVD. It's a different process than burning an MP3 file or a document to a disc because your CD/DVD burning software must "assemble" the contents of the ISO file onto the disc.


ISO image files are often used to distribute large programs over the Internet due to the fact that all of the program's files can be neatly contained as a single file - the ISO file.ISO images end in the file extension ISO.


How to Create a Bootable Disk From ISO


The ISO image format allows you to store virtual backups of your CDs and DVDs on your computer's hard drive. The contents of your CDs or DVDs are stored in the ISO format, along with its boot information, allowing you to create physical copies as you need them. And unlike standard burning software, an ISO utility like PowerISO--which is capable of reading the ISO format and its boot information--can create a bootable, physical copy of your virtual image file.


1.Navigate your web browser to the official homepage of PowerISO and download a copy of the utility. After the download has completed, close all other programs and install it. After the software is installed, PowerISO will need to reboot your computer before it is ready to run.

2.Launch the program. Click "Open" located in the top left corner of PowerISO. Use the File Explorer window that pops up to locate the ISO file on your computer. Select the file. Click "Open" in the bottom left corner of the Explorer window.

3.Insert a blank CD or DVD into your computer's CD/DVD-ROM drive. Click "Burn" located near the top right corner of PowerISO. The Burn Image File menu will appear.

4.Navigate to the heading labeled "Burning Parameters" and place a check in the box labeled "Verify Written Data." Click "Burn" at the bottom of the window to burn a physical copy of the ISO image file.
