The extract and reconstruct method is a workaround at best, and it requires knowledge of how to properly reconstruct the ISO from exactly the same properties (and there are a bunch of them) as the original.

The desired behavior is to edit the ISO "in place" as you can other archive types, thus preserving (and not caring about) whatever properties are asisgned to the ISO. Why should I have to extract and rebuild an ISO to simply add a file to it? It's unnecessary and very error prone because--as I mentioned--the reconstruction of the ISO requires making many decisions about the ISO properties that a normal user would find very difficult to get correct.

Additionally, I would have to buy the PowerArchiver ToolBox, for which I do not have a license. I only own PowerArchiver Standard.

Is there some sort of patent on this process? It seems PowerISO and its clones (MagicISO, WinISO, UltraISO) are the only tools that can do this and have some sort of monopoly hold over it.

But thank you for the reply. I was wondering when someone was going to make any comment at all.
