Deleting and copying files using batch file

Question

Im trying to copy files from one drive to another using a batch file, Which works! but we keep Changing file names on our main file which creates addition copys with diffrent names everytime its run. I dont want to delete the Copy file entirely bacause of the length of time the copy takes just to copy. I would like to Compare the 2 files and delete the files that are no longer on the main drive here is the test that im working on. Thanks for any help you can give me.

@echo
cls
If not exist "C:\Users\Jeremy\Desktop\Test Main\*.*" "Del "C:\Users\Jeremy\Desktop\Test Clone\*.*"
xcopy "C:\Users\Jeremy\Desktop\Test Main\*.*" "C:\Users\Jeremy\Desktop\Test Clone\*.*" /D /C /E /S /I /Y /V /H /R /F /d:01-01-1998
pause

:abort
echo You pressed CTRL+C to end the copy operation. 
goto exit 

Answer 1

您可能想研究robocopy ，特别是使用/mir开关，它将源文件夹镜像（复制所有新文件并删除所有不再存在的文件）到目标文件夹。

Answer 2

Thanks This does work

@echo
cls
robocopy /MIR "C:\Users\Jeremy\Desktop\Test Main" "C:\Users\Jeremy\Desktop\Test Clone"
pause

:abort
echo You pressed CTRL+C to end the copy operation. 
goto exit 

But I would still like to understand if anyone can or wants to take the time to correct my original question

Answer 3

Try:

@echo off
cls
If not exist "C:\Users\Jeremy\Desktop\Test Main\*.*" "Del "C:\Users\Jeremy\Desktop\Test Clone\*.*"
xcopy "C:\Users\Jeremy\Desktop\Test Main\*.*" "C:\Users\Jeremy\Desktop\Test Clone\*.*" /D /C /E /S /I /Y /V /H /R /F /d:01-01-1998

If %errorlevel% EQU 2 (
echo You pressed CTRL+C to end the copy operation.
)
pause
