I thought your question was clear for what it’s worth. If it was Windows 3.0 era you’re probably looking for ViewMAX (from the same company as DR-DOS, which was an MS-DOS compatible operating system, maybe that’s where the ‘D’ comes from?). I vaguely remember reading (or maybe watching) a good feature about it online a while ago but I can’t find it unfortunately.
To be fair, I was quite vague. I think there are multiple right answers… but I recalled one starting w/a ‘D’ and that’s what I was trying to recall.
