就是用SD卡，现在非常便宜了，128GB不到$20，250GB不到$40。你可以先加一个小的，
比如128GB，以后不够了，大的更便宜了，再换到256GB、512GB。

不需要任何工具，也不要开机箱，把所有的目录copy到新的SD卡上就是了。然后老的小
SD可以用到其它设备上去，比如手机和相机等。

用Windows自带的mklink，可以把SD卡和现有的硬盘融为一体。比如你可以把：

c:\program files\MicrosoftOffice

移（move）到SD卡上面去：

d:\program files\MicrosoftOffice

然后用mklink命令再映射回去（junction）：

mklink /j “c:\program files\MicrosoftOffice” “d:\program files\
MicrosoftOffice”

你都不需要重装Office，或者做任何变更，就把原来硬盘里的空间腾出来了。

如果你不喜欢敲命令行，你可以下载Link Shell Extension。先右击SD卡上的一个目录
，选择Pick link source，然后在硬盘上右击，选择Drop as junction。不能再容易。

Junction的另一个非常好的用处是备份。我把所有我需要备份的目录都junction到一个
目录里，比如c:\to_backup。然后每次做备份的时候就只要robocopy这一个目录，不容
易漏掉啥。

Write all those context names into /opt/course/1/contexts . Next write a command to display the current context into /opt/course/1/context_default_kubectl.sh , the command should use kubectl . Finally write a second command doing the same thing into ...
