Options System Snapshot / INI Monitoring page lists the INI files which must be considered by the System Snapshot tool when taking snapshots.
You can use the buttons under the list to add new items, modify existing ones or delete them. Please note that you don't have to delete an item just to exclude it from the processing; instead, you can simply remove the check mark from the box next to it.
The button Default restores the default settings for this feature, including recovery of the items deleted by you and deletion of the ones added by you.
