列出USB設備，選擇一個備份批處理文件

Question

，所以我正在寫一個小的批處理文件，做一些有用的東西，但我有一個特定的麻煩，我使用這個命令：

set /p choice="Press Enter to show available Backup USB Drives" if "%choice%"=="" wmic logicaldisk where drivetype=2 get deviceid, volumename,

其工作，並將其顯示可用的USB設備，但這些設備我想創建一個列表，以便用戶可以選擇作爲備份驅動器要使用的驅動器，任何的幫助深表感謝

Answer 1

這將顯示所有可用的驅動器和測試，如果答案是一個有效的驅動器（目前在列表中）：

@echo off 

setlocal enabledelayedexpansion 

:: Creating a list with all USB drive 

for /f "delims=" %%a in ('wmic logicaldisk where drivetype^=2 get deviceid ^| find ":"') do set "$List=!$List! %%a" 

::Your Menu 

:menu 
set /p choice="Press Enter to show available Backup USB Drives" 
if "%choice%"=="" goto:USB 
goto:menu 

exit/b 

::Displaying available drive and asking to choose one 

:USB 
echo Avaiable Drive ==^> !$List! 
set /p "$Drive=Enter the letter of the Backup drive : " 
cls 

::Testing the availibility of the choosed drive in the List 

echo !$List! | find /i "%$Drive::=%:" && Echo drive OK || Echo drive do not exist && goto:USB 

代替Echo drive OK的你可以做一個Goto:next和使用!$Drive!作爲選用的車程。

Answer 2

:-)我創建了一個用戶輸入的變量，而不是從實際列表中選擇，用戶只需鍵入驅動器盤符，例如：G：我意識到即使我創建了一個實際列表，用戶仍然需要輸入他想要使用的驅動器，爲什麼不使用鍵入的驅動器盤符作爲變量並將其添加到xcopy命令行，這裏是小實用程序的整個代碼，稍後我將添加一個小文件夾樹選擇一個備份源比手動輸入更好
