If you don’t happen to have a good file manager program, something like this could certainly be useful. However, I’ve been an everyday user of the ZTree file manager (from ZedTek, and a successor to the old XTree) for many years now, and I’m confident that it covers pretty much everything that this one does, plus considerably more. At the same time, I have checked out others like Total Commander and XyPlorer, finding them overly cluttered and less straightforward in operation when compared to ZTree. So I have not found any good reason to change.
