Which still is very useful in a DosBox.

I also remember M602 and Volkov Commander from those days.

There is also the Star Commander [1] which supports Commodore 64 disk images and physical drives using the X1541 interface [2]:

I used Volkov Commander when I needed long file names support.

What is M602?

File manager for MS-DOS (from a Czech company S602) that I used the most, probably.
