Have you tried disk master 2?
Early-2016 I bought an original copy of Disk Master off of Ebay. It wouldn't run on my 1200, unfortunately. To be honest, I'd forgotten about it because I wound up putting it on a shelf and had mentally filed it as a failed experiment. But now that I'm in 1.3 Land, I should try it again.
That being said, I'll be surprised if it has much more to offer than DirOpus. Might be fun to do a side-by-side comparison, though. I had DirOpus launch via Startup Sequence as a slim little toolbar, but I've since commented that out as the inaccurate clock drives me nuts.
On a side note. when I used DirOpus to make icons for my ADF files that I migrated over from the PC, it made them look like cute little composition books you might have used in school. I wonder what other icon variations it has stuffed up its sleeves? Incidentally, if you ever want to give DirOpus a spin, I bet I can make ADFs of the versions I have.
