There is an old trick from Dos days (still valid in all windows under cmd prompt or even command.com) when we wanted to create a quick file without loading up edit (edit.com) was to use copy con.有一个重施故技，从DOS天（仍然有效，在所有Windows下cmd提示或什至command.com ）时，我们要创造一种快速的文件不加载了编辑（ edit.com ） ，使用副本结论。 The exact syntax is:确切的语法是：
copy con filename 复制结论文件名

Subsequent lines you type are copied to the file.随后线您输入复制到该文件。 You could end the content by pressing Ctrl-Z and then pressing Enter.你可以结束的内容，按下Ctrl - Z型，然后按Enter键。
