Well thats your choice. I for one would rather have one program that does everything, than having to get 10 programs to do the same thing.
This is what the problem is with the amiga today, you end up with lots of programs just to do one thing.
I have two programs that can do the same thing: DirectoryOpus & Diskmaster.
I've configured it so that if i double click on any file (text, pictures, librarys e.o.),
I can see picture, text or info from versions of librarys and other programs. Heck,
i can even see the contents of lha, lzx, adf and dms archive files by double clicking
on the archive file.
So no need for another expensive "new" multiple viewer.
