ISO, ISZ files
Maybe you know the feeling, when you download an older disk image from internet only to realize it's in some rare format. ISZ format is one of them, it is the default image format of UltraISO, which itself is a commercial app - and not everyone is interested of spending 30 bucks only to access single file. You could use the trial version of UltraISO, but it has pretty severe limitations.
In this small tip we will show you how you can quickly convert CD sized ISZ images to standard ISO image - for free.

For purpose of converting ISZ to ISO format , we have picked AnyToIso converter from Crystalidea. It's Lite (free) version can flawlessly work with images in the size of CD (870 MB), which should be enough for most images found in internet.
