windows10 C盘空间转移

windows10-subsystem-for-linux-03-C盘空间转移

下载安装的WLS默认在C盘，如果C盘重装就会导致WLS直接受影响，同时因为一般C盘空间有限，如果长期使用，可能会导致系统速度越来越慢，因此选择将WLS迁移到其他盘，我选择的是电脑自带的固态硬盘。

简介

Win10 mklink

mklink 命令是 Windows 自带的命令，除了在 Win10 系统下使用，在比较早的系统比如 Win 7、Win Vista、Win 8 和 Win 8.1 也都是可以使用的。不过在除了 Win 10 之外的系统里使用，是必须使用管理员权限的，否则会提示“你没有足够的权限执行此操作。”，当然经过我验证，Win 10 有时候也是需要管理员权限的。

LxRunOffline

A full-featured utility for managing Windows Subsystem for Linux (WSL).

  • Install any Linux distro to any directory on your computer.
  • Move an existing installation to another directory.
  • Duplicate(copy) an existing installation.
  • Register an existing installation directory. This enables you to install to a USB stick and use it on different computers.
  • Run arbitrary Linux commands in a specified installation.
  • Configure default user, environment variables and various flags.
  • Export configuration to an XML file and import from the file.
  • Export an installation to a tar file.

准备工作

MKLINK [[/D] | [/H] | [/J]] Link Target
        /D        创建目录符号链接。默认为文件符号链接。
        /H        创建硬链接而非符号链接。
        /J        创建目录联接。
        Link      指定新的符号链接名称。
        Target    指定新链接引用的路径(相对或绝对)。

这个地方我们使用 /J创建一个目录联接 示例:

mklink /J "C:\Users\Jermaine\AppData\Local\Packages" "E:\Users\Jermaine\AppData\Local\Packages"

mklink /D "C:\Users\Jermaine\AppData\Local\Packages" "E:\Users\Jermaine\AppData\Local\Packages"

windows 应用默认存储位置

C:\Users\Jermaine\AppData > E:\Users\Jermaine\AppData

将地下的文件直接复制到E盘相同路径
