I alwas use Doscontrol for my amiga's.
Great advantage is it works out off the box with just one exe and from workbench 2.0 to 3.1.
It is extremely fast but has bugs with P96 screens.
Anyways just for copying/renaming/formatting around this is my favorite.
And it even has a disk optimizer and repairtool in the program.
For small amiga's a neat program but only in german.(not the commands).
See aminet..
