Specifies the maximum number of days that Creo ModelCHECK reports are kept.

When you start Creo Parametric and Creo ModelCHECK is initialized, the directory specified by the DIR_REPORT configuration option is scanned for reports that are older than the specified number of days. If any are found, they are deleted.

If the HTML_MAX_DAYS configuration option is not specified, the purge is not done.
