You may find out some file in destination of folder is still old one, but rest of files are overwrited correctly.
The rule is depended on date time of file. The new one will keep and not be overwrited, but you can not detect it until something finally goes wrong.
Why? We can simply do it like Windows or Linux, right?
拖拉合併時,日期比較新的檔案,就被忽略而不覆蓋?這是個難以被注意的規則,直到你的作品出錯了,你甚至還無法意識到是這個原因造成的。
為什麼需要如此特殊的行為呢?我們可以像 Windows 和 Linux 一樣簡單,不是嗎?
