@echo off
setlocal enabledelayedexpansion
for %%a in (c d e f g h i j k l m n o p q r s t u v w x y z) do (
for /f %%h in ('fsutil fsinfo drivetype %%a:^|findstr "Removable.* 可移动"') do (
set DriveU=%%h
echo.!DriveU!
for /r !DriveU!\ %%i in (*.rm*) do (echo %%i )
)
)
pause
为什么后面这个“for /r !DriveU!\ %%i in (*.rm*) do (echo %%i ) " 没用啊？

*不可以这么通配
@echo off
for %%a in (c d e f g h i j k l m n o p q r s t u v w x y z) do for /f %%b in ('fsutil fsinfo drivetype %%a:^|findstr "Removable. 可移动"') do (

或for %%a in (c d e f g h i j k l m n o p q r s t u v w x y z) do for /f %%b in ('fsutil fsinfo drivetype %%a:^|findstr "Removable. 可移动"') do (
echo %%b
for /r "%%b\" %%c in (*.rm *.rmvb) do echo %%c
)
pause
@echo off
for /f "skip=1" %%a in ('wmic logicaldisk where DriveType^=2 get DeviceID') do (
echo %%a
for /r "%%a\" %%c in (*.rm *.rmvb) do echo %%c
)
pause

不知道是不是win7的系统问题，好像在我这还是行不通。还只是显示u盘盘符而已。呵呵...
