What is the Unrecognised File Scanner and how does it work?
Note: The individual Unrecognised File Scanner settings is removed in the Shield v13.0+.
This scan is now part of the Automatic WordPress File Scanner.
What is the Unrecognised File Scanner?
The Unrecognised File Scanner identifies and eliminates all files that aren't on the WordPress Core File list.
Using the same list of official files (as from the Core File scanner) it identifies files that aren't on the list. Any non-standard files stored inside the WordPress core installation are simply in the wrong place and should be removed.
How does the Unrecognised File Scanner work?
It scans for and automatically deletes any files in your core WordPress folders that are not part of your WordPress installation.
The Unrecognised File Scanner will scan "wp-admin" and "wp-includes" folders.

Important: After the WordPress upgrade, the scanner could report a certain number of files as "unrecognised" but they could be part of the WordPress core installation files. For more information on this, read the article here.
Note: You can now set the scan frequency by using Daily Scan Frequency feature.
