Below is the solution I found,I tried to raise a dialogue box through batch file after completion of the job that processes all the files in a folder1 and move it to folder2 one by one after processing.
sqlcmd -S myserver -d "master" -Q "my_procedure"
:loop
ping 1.1.1.1 -n 1 -w 10000 > nul
IF EXIST "D:\folder1\*.csv" goto :loop
start %comspec% /c "mode 40,10&title Process Completion-Confirmation&color 1e&echo.&echo. Process has completed.&echo.&echo.Press a key!&pause >NUL"
