There are rarely directories named > 'My.zip", but I could imagine a directory Myzip to exist. `Myzip' would be matched by ".*" (the dot here is a special character in the regexp, matching any character). But if you have a directory `My.zip' it would have already been matched by "\.zip\'", so here you'll have to add the Lisp expression to prevent the wrong shell command from applying to it. However, what I wrote previously was insufficient: once the match is satisfied, no further patterns are tested. So if you want the shell command suggestion with `!' in Dired to be unzip on a non-directory file "Myfile.zip" and to be zip on a directory "Mydir.zip", the entry in dired-guess-shell-alist-user should be this (modulo whatever your actual shell commands are): ("\\.zip\\'" (if (file-directory-p (dired-get-filename)) "(zip ? &>/dev/null &)" "(unzip ? &>/dev/null &)")) (This time I actually tested it, so I hope it now really works for you!)
