找到可移动驱动器的数量 [英] find number of removable drives

问题描述

我是新手，但最近遇到了在连接本地磁盘的'n''数量的USB磁盘上运行批处理文件的问题。如果有人可以在批处理脚本文件中帮助查找附加到系统的磁盘数，请在n个磁盘中运行批处理文件。在所有可移动磁盘上运行批处理文件并退出。



感谢预期

推荐答案

基本上，这一切都是通过WMI完成的： http://en.wikipedia.org/wiki/Windows_Management_Instrumentation [ ^ ]。



In PowerShell（强烈推荐）：

Basically, it all is done via WMI: http://en.wikipedia.org/wiki/Windows_Management_Instrumentation[^].

In PowerShell (highly recommended):

drives = Get-WmiObject Win32_Volume |其中{

drives = Get-WmiObject Win32_Volume | Where {

_.DriveType -eq 2}

_.DriveType -eq 2 }

这里，驱动器类型2表示可移动驱动器



在传统批次中：

Here, drive type 2 means "removable drive"

In legacy batch:

@wmic logicaldisk get volumeName, description, deviceId

添加一些代码来计算它们。
