To change the number of days to retain mailpiece zip files to 60 days (instead of 90)
Go into SQL Developer.
run the following SQL
UPDATE CLEANUPFILES SET DELETE_ZIP_DAYS_OLD=60 WHERE NAME='costmanager';
To check and make sure the setting took.
Look again the next day (or 12+ hours later). About 1/3 of the zipped files (the oldest ones) should now be deleted if it's changed from 90 days to 60
