VSCode 的插件目录在各平台下的默认位置如下：
Windows %USERPROFILE%\.vscode\extensions
macOS ~/.vscode/extensions
Linux ~/.vscode/extensions
Windows 系统中 VSCode 编辑器的插件目录默认在 C 盘，extensions 目录会很大，我们可以通过自定义 VSCode 插件安装位置来解决：
方法一（推荐，不用每次重启电脑）：
前提是已安装 VSCode，并且已将其添加到了环境变量 path 中。打开 VSCode，然后在打开的 VSCode 中点击 Terminal 菜单栏的 New Terminal 菜单，输入命令code --help 命令可以查看帮助，输入 code --extensions-dir "your extensions dir" 命令来指定插件目录。如下所示：
PS C:\Users\Vincent Huang> code --help
Visual Studio Code 1.44.2
Usage: code.exe [options][paths...]
To read output from another program, append '-' (e.g. 'echo Hello World | code.exe -')
Options
-d --diff Compare two files with each other.
-a --add Add folder(s) to the last active window.
-g --goto Open a file at the path on the specified
line and character position.
-n --new-window Force to open a new window.
-r --reuse-window Force to open a file or folder in an
already opened window.
--folder-uri Opens a window with given folder uri(s)
--file-uri Opens a window with given file uri(s)
-w --wait Wait for the files to be closed before
returning.
--locale The locale to use (e.g. en-US or zh-TW).
--user-data-dir Specifies the directory that user data is
kept in. Can be used to open multiple
distinct instances of Code.
-h --help Print usage.
Extensions Management
--extensions-dir Set the root path for
extensions.
--list-extensions List the installed
extensions.
--show-versions Show versions of installed
extensions, when using
--list-extension.
--category Filters installed
extensions by provided
category, when using
--list-extension.
--install-extension Installs or updates the
extension. Use `--force`
argument to avoid
prompts.
--uninstall-extension Uninstalls an extension.
--enable-proposed-api Enables proposed API
features for extensions.
Can receive one or more
extension IDs to enable
individually.
Troubleshooting
-v --version Print version.
--verbose Print verbose output (implies --wait).
--log Log level to use. Default is 'info'.
Allowed values are 'critical', 'error',
'warn', 'info', 'debug', 'trace', 'off'.
-s --status Print process usage and diagnostics
--prof-startup Run CPU profiler during startup
--disable-extensions Disable all installed extensions.
--disable-extension Disable an extension.
--sync Turn sync on or off
--inspect-extensions Allow debugging and profiling of
extensions. Check the developer tools for
the connection URI.
--inspect-brk-extensions Allow debugging and profiling of
extensions with the extension host being
paused after start. Check the developer
tools for the connection URI.
--disable-gpu Disable GPU hardware acceleration.
--max-memory Max memory size for a window (in Mbytes).
--telemetry Shows all telemetry events which VS code
collects.
PS C:\Users\Vincent Huang> code --extensions-dir "D:\development\tools\VSCode-win32-x64-1.46.1\resources\app\extensions"
PS C:\Users\Vincent Huang>
方法二
右键桌面的 VSCode 快捷方式，点击属性，将目标由
D:\development\tools\VSCode-win32-x64-1.46.1\Code.exe
修改为：
D:\development\tools\VSCode-win32-x64-1.46.1\Code.exe --extensions-dir "D:\development\tools\VSCode-win32-x64-1.46.1\resources\app\extensions"
添加了code --extensions-dir "your extensions dir" 命令之后就会使用新的插件目录。
