Problem to debug files databases

Hello to all, Now We have with the version 7 (7001) of Firewall Analyzer, In general the operation of the application is good only but We have a downside, In the application we configure in the section Data Storage Options that Database and log archive were 2 months but when We review the folder /../ManageEngine/Firewall/mysql/data/firewall, we detect files of more 3 moths ago, mainly ipd files. I once wanted to delete these files manually or by an application to connect to the database manager. But I will not jeopardize the operation of the application and so I did not.

The question is:

Is there any way to make debugging IPD files, either from the application or from any manager without affecting the operation of the application?

Thanks for the attention.
