This is an update on MagicDisc discussed in several very old threads (before 2010).
There is a Wikipedia page: https://en.wikipedia.org/wiki/MagicISO#MagicDisc
Here is an excerpt:
"MagicDisc, sometimes known as MagicISO Virtual CD/DVD Manager is a freeware virtual drive counterpart to MagicISO.
It is a separate application needed to mount discs virtually.
MagicDisc can also decompress UIF images to ISO format."
Note that the link to MagicDisc (in the Wikipedia page) cannot be found (404 Error)
MagicDisc can be part of a "UIF2ISO" toolkit.
Softpedia: https://www.softpedia.com/get/CD-DVD-To ... -ROM.shtml
has a working download link for Win 64 systems: "MagicDisc Virtual DVD / CD-ROM v.2.7 Build 106 "
Their link for Win 98 is broken
I have NOT tested MagicDisc, because, sorry I don't have time, and also currently I have no need (I mean ... no motivation) for this type of application.
