    Files in the destination folder will have the same names and extensions as the original receiver log files. Before downloading the current log file in the destination folder, PC-CDU will check if there al- ready exists a file with the same name in this folder. If such a file is found there, the user will be prompted to select either A p p e n d or O v e r w r i t e .
