Win32 Disk Imager

Win32 Disk Imager is a utility for reading and writing a disk image file to an external storage device.

The application is open source and free to use, so you can use the program for as long as you like, without any limitations whatsoever.

You have access to a user-friendly interface where all you need to do is to import your disk image file (IMG format), select the preferred task type and an external device, and the app will take care of the rest. As long as you know how to work with IMG files, you shouldn't have any difficulties using this application.

The program works with various external storage devices (USB sticks, flash drives, etc.), but it crashes if you are using a Ramdisk.

Another thing you need to take into consideration is the fact that the utility might take a while to complete disk image writing tasks.

To sum things up, Win32 Disk Imager proves to be a smart addition to your collection of Windows applications as long as the aforementioned aspect doesn't mean much to you. Otherwise, I'd suggest you to try a different program to read and write disk image files to storage devices.
