By default Forensics uses up to 1 GB of disk space on the client computer for data. You can configure more space for Forensics storage, but not less.
After the threshold is reached, the oldest data is deleted.
Change the Maximum Forensics Database size in the Disk Usage area of the Monitoring and Exclusions Action.
You can configure more settings related to space usage in GuiDBedit Tool (see sk13009) or dbedit (see skI3301).
Important - Do NOT use these tools unless instructed by Check Point Support or R&D. Incorrect use may corrupt settings in the management database.
