I like
XLent.
That came bundled with X-Copy.
XLent up to Ver. 2.40 runs on 1.3 Amigas. It is only 28kb in size and therefore very well usable from floppy.
But its rather limited in Features. Beside the basic features like copy, move, rename, makedir it can view files as text and hex. And you can also assign custom commands. But that feature seems to be buggy. If you want to pass a file to ed you have to compose the full path from two variables: %a/%f. That means path and filename.
But if the file is in the rootdir like df0:file, this command expands to df0:/file. So I built a tool to fix executes with defunctional paths.
