Hey! Straight to the point: - Colleague running Sierra on a Mac Pro just moved a file from a memory card to an external drive. - After the transfer was done, he formatted the memory card and then sent it away. - Back on his Mac Pro, he accidentally hit CMD+Z while in the Finder-window instead of the app he was using. - Finder seem to have undo:ed the "move from memory card to the external drive"-move, but since the external drive is not plugged in anymore the file obviously cannot be found on that drive any longer. Questions: What actually happened to the file? Is there a way to redo the undo (it's currently greyed out). Grateful for all the help. Important file and a not so happy colleague. (edit, got the process of from what device to what wrong).
