Begin Batch

When a Begin Batch message is received, the temporary directory DR_TMP_DIR is first created in the target directory, if not already created. Then a target file is created and opened in the temporary directory.

End Batch

When an End Batch message is received, the target file in DR_TMP_DIR is first closed and then the Command, if specified in After Treatment, is executed. Finally, the file is moved from the temporary directory to the target directory.

Cancel Batch

If a Cancel Batch message is received, the target file is removed from the DR_TMP_DIR directory.
