There is usually no need to scan every single file. We've added the few most important file types:
If you want to add another file type, simply take a new line in the text box and provide the file type extension:
Note: You do not need to provide the dot(.) for the extension. Just the final letters. So if it's a PHP file, you provide "php"
If you want to scan every file, regardless of type or extension, then clear all items from the list. - This is not recommended as it will greatly increase scan times and also lots of notifications if a particular plugin writes temporary files to its own folder.
