The Shareware Larsen Commander ist a very good norton-like file manager (with two sides each showing a directory). The Shareware fee is 40 US-$, It is available in functionally identical versions for Windows and for OS/2 and eComStation. The program is able to open ZIP files like directories und has got a lot of very nice details, for example the file copy success dialog:
In the lower line ("dir"), you can enter commandline commands. The black commandline output can be made invisible, of course.
You should remember a few keycodes:
Ctrl-mouse movement: selecting files
Einfg: also selecting files
Ctrl-Q: size of directories in bytes
Shift-Alt-Cursor right/left: show right/left directory on the other side
Shift-F6: rename a file.
