有了这些选项，您可以在进行实时连接时精确地复制文件，关闭掉连接，处理它，然后在您完成处理以后将它们上传回到服务器上。

With this option, you explicitly copy files locally while you have a live connection, close the connection, work on the files later, and upload them back to the server after you have finished.

有更多的错误选项需要排除，而如果个体的独特性很低，那就意味着出现更多的幽灵般的复制体、更多认错的可能。

There are more distracters to sift through, and if individual uniqueness is low, that means more doppelgangers, more cases of mistaken identity.
