It could be a file folder or a shoebox or anything you like, but I think it's good to keep each idea on a separate piece of paper.

它可能是一个文件夹或一个鞋盒或任何你喜欢的东西，但是我认为把你的每个想法保留在每一张单独的纸上这是有好处的。

Just as you keep copies of all letters in a paper file folder, you should keep copies of all letters on your computer in the directory for that client.

就像把信函的副本保存在一个纸文件夹中一样，您可以将信函的电子副本保存在电脑中专门为该客户建立的文件夹中。

If you create a directory (folder) on your computer for every client, you can keep all letters, documents and work for that client in one easy-to-find place, just like your paper file folder.

您可以在电脑上为每个客户建立一个单独的文件夹，这样就可以将该客户的信函、文档、工作记录全都放在该文件夹下，就像放在一个纸文件夹中一样，查找起来方便多了。
