So all you want to do is create an ISO image containing several files? :confused:

Yup

Put all the items you want in the ISO into a folder

Launch disk utility

From the Menu Bar go to Images>New from folder

Select the folder with the items

Enter a Save as name

And Image Format must be DVD/CD master

The resulting file will be filename.cdr, which you can rename to .iso
(They're the same thing, that's what the DVD/CD Master are for. If you chose read-only renaming it ISO won't work on a PC because it'll make a HFS+ volume instead of a CD volume, I believe.)

Ok to clear up my misunderstanding, I want to actually join the files.

what kind of files are they?

Ok to clear up my misunderstanding, I want to actually join the files.If you really want to just jam the files together end to end into one big chunk (which is, I think, what "copy /b" does), you want to fire up the Terminal and use the "cat" command. The syntax, I believe, is "cat file1 file2 > file3", where the contents of file 1 and file 2 will be joined into file3, leaving the original two alone.

Check out the man page for cat to get an idea of what the options are.

There are of course graphical tools to do this, but cat is the closest to the command line tool you mentioned before.
