Ah. This "arc" is not an archiver -- it's a file copier, and one of the most-used tools I have ever used on OS-9. I will type out the help screen:

arc -?

Usage: arc [-acdeflmuv] from_dir to_dir
     a = all files
     c = confirm file if not there
     d = confirm non-existant directory
     e = confirm existing directory
     f = prevent copy of files
    ln = only n levels of the tree (1..9)
     m = do multilple (all) directories <- typo not mine
     v = verify the copy
     u = force uppercase for comparisons

I think Bill Pearce (?) was the one who said he also used it. I do not recall where I got it from, but it's amazing. I have never had it fail until tonight ;-)
