我创建了一个批处理文件，用于从一个驱动器运行到另一个驱动器的按需机器人副本。问题是外部驱动器并不总是具有相同的盘符。
这是代码。该文件有效，并为我提供了我预期的行为。我想知道是否有办法简化这一点。
:: This is my robocopy script
IF EXIST "E:Appraisal Service" goto robocopy1 else goto nextdrive1
:robocopy1
robocopy "Z:Appraisal Service" "E:Appraisal Service" /E
:nextdrive1
IF EXIST "F:Appraisal Service" goto robocopy2 else goto nextdrive2
:robocopy2
robocopy "Z:Appraisal Service" "F:Appraisal Service" /E
:nextdrive2
IF EXIST "G:Appraisal Service" goto robocopy3 else goto nextdrive3
:robocopy3
robocopy "Z:Appraisal Service" "G:Appraisal Service" /E
:nextdrive3
IF EXIST "H:Appraisal Service" goto robocopy4 else goto nextdrive4
:robocopy4
robocopy "Z:Appraisal Service" "H:Appraisal Service" /E
:nextdrive4
IF EXIST "I:Appraisal Service" goto robocopy5 else goto nextdrive5
:robocopy5
robocopy "Z:Appraisal Service" "I:Appraisal Service" /E
:nextdrive5
IF EXIST "J:Appraisal Service" goto robocopy6 else goto nextdrive6
:robocopy6
robocopy "Z:Appraisal Service" "J:Appraisal Service" /E
:nextdrive6
IF EXIST "K:Appraisal Service" goto robocopy7 else goto quit
:robocopy7
robocopy "Z:Appraisal Service" "K:Appraisal Service" /E
:quit
exit
提前致谢
for %%a in (E F G H I J K) do IF EXIST "%%a:Appraisal Service" robocopy "Z:Appraisal Service" "%%a:Appraisal Service" /E
%%a依次设置为每个目标驱动器号，如果目标驱动器号上存在该目录，则执行复制。
这是
最终的代码。感谢Magoo（他是对的）。我想出了我的不幸（我错过了一个导致它不起作用的"："）。
