My personal favorite is a little less obvious.The old MSDOS "ren" (rename) command would give this "duplicate file name or file not found" error, which sounds perfectly harmless until you parse it."Duplicate file name" = "Filename Already Exists""File Not Found" = "Filename Doesn't Exist"So in short, the error says "The filename exists or it doesn't." Abusive comment hidden. (Show it anyway.)
