Dear Emacs maintainers, The behavior I have is odd at best, but the situation is simple: given a folder 'test', I want to make a copy of it in another folder. In practice (keyboard commands are between <>): * Open Emacs, <M-x dired> in any folder. * <+ test> to create a folder 'test'. * <+ target> to create a folder 'target'. * Move on 'test' then <C target/> to copy it in 'target', <yes> to copy recursively. So far so good, the empty 'test' folder is copied as expected. Assuming there is some change in this folder, we want to copy it again to the same place: * Move on 'test' then <C target/> to copy it in 'target'. * Dired asks for confirmation to overwrite it, and if yes copies it again. Now the weird behavior. With '(setq dired-dwim-target t)': * Open a second window <C-x 3>. * Move to 'target' in this window, as to have 'target' on the right window, but the initial folder on the left window. * In the left window, move on 'test' and <C> to copy it again, DWIM will suggest directly 'target/', so all that is needed is <Enter>. Note that there is no question to overwrite it or not. Visiting 'target' now shows the 'test' folder, but inside it a second copy of 'test'! Even weirder: * Create an empty file in the original folder (<C-x C-f bla>, then <C-x C-s> to save it, and <C-x k> to kill it). * Select in the left window both 'test' and 'bla' with <m>. * <C> to copy them, DWIM will suggest directly 'target/', so all that is needed is <Enter>. Now it asks for confirmation to overwrite and copies 'test' together with 'bla' in 'target' as expected! (of course, this example mostly uses empty files/folders, but that's really just for the demonstration.) Mathieu.
