:COPY
xcopy %drive% D:\Backup
goto :LOOP
我没有批次的经验,我想知道,我该怎么办? : 如果不存在可移动磁盘,请不要转到COPY并转到LOOP?

让wmic
为您进行过滤:
:LOOP
for /f %%d in (
'wmic logicaldisk where description^="Removable Disk" get caption ^| find ":"'
) do (
xcopy %%d D:\Backup
)
goto LOOP

:LOOP
:: Finds Removable Disk Letter
for /f "tokens=1-3" %%a in ('wmic logicaldisk get caption^, description') do (
if "%%b %%c"=="Removable Disk" set drive=%%a
if not exist "%%a" goto :LOOP
)
:COPY
xcopy %drive% D:\Backup
goto :LOOP
基本上,如果该驱动器不存在,它将返回:LOOP
,如果它存在,它将自动落到:COPY
。
