The following review written by one of the Software Informer contributors applies to version 5.8
PowerISO can process image files of various types of discs. Fortunately, it supports a wide array of formats, including ISO, NRG, DAA, BIN, and VCD. This tool can help you perform most operations related to disc images. For instance, you can use it to open an ISO image and burn it onto a disc. Likewise, it can extract the contents of an ISO file. Other operations supported include creating new ISOs, editing existing ones, encrypting their contents, splitting files as well as converting them between any of the supported formats.
The application has an intuitive interface similar to that of a file manager. Its toolbar can help you access most common operations. This way, you will find it very easy to burn or rip audio CDs. Likewise, you can use the application to create video CDs. However, I did not find a way to create video DVDs or BDs.
You will probably agree that mounting a disc image to a virtual drive is one of the most attractive features of this application. Moreover, you can also create bootable data discs or images. Finally, it also supports various operations involving USB drives, such as creating a bootable USB drive.
In general, the ones mentioned above are just some among the huge number of features available from this application. Thus, it is one of the most comprehensive tools intended to manage disc images.
