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.
if it is that good, why dont you send the config files to Aminet so that others can benefit from your finding ?
