How to Extract an ISO File to USB Flash

ISO files are files that can be loaded onto a CD or DVD using a variety of programs. Then, you can set your computer to boot from this CD/DVD to install the software. Many open-source operating systems are distributed as ISOs. Putting an ISO image file onto a USB flash drive can be extremely useful, especially if you want to move the image to another computer.

ISO files can be many gigabytes in size.

Step

Obtain a USB flash drive that exceeds the size of the ISO file you wish to transfer. Many ISO files can be greater than 2 GB in size, so a high-capacity flash drive (4 GB or greater) is necessary.

Step

Find the ISO file on your computer.

Step

Insert your flash drive into a USB port on your computer.

Step

Open "My Computer" ("Computer" in Windows 7) and find your flash drive in the "Devices with removable storage" section.

Step

Drag the ISO file from its current location to your flash drive. If you just want to copy the file to your flash drive (leave a copy on your desktop as well), right-click the ISO file and select "Copy." Then, open up your flash drive contents, right-click and select "Paste."
