DCM creates the generate_directory the first time a generate operation is performed in a database. DCM creates the receive_directory during the DCM initialization of a database so it can receive transfers.
During normal operations, DCM uses these directories for temporary creation and extraction of the transfer package. When DCM completes an operation, it removes the temporary files. Occasionally the transfer package files are not removed. Therefore, periodically check the generate_directory and receive_directory and remove any unneeded files.
