Exclude folder pattern

[simbun]

Is there any way I can tell MinimServer to ignore the ext4 'lost+found' folder as it results in a WARNING every time I do a rescan?

Code:

Warning: error scanning file '/media/music/lost+found': java.nio.file.AccessDeniedException: /media/music/lost+found

I've attempted many permutations in the excludePattern property but it still attempts to descend even though it's excluded.
Changing the excludePattern to 'Adele' does exclude the Adele folder, but if I change the permissions to 700 I get the same error, so I assume that's just the way it works.

I know I can move everything down a folder - or live with the warning - so it's not the end of the world, I just know how meticulous you are so thought there might be a solution.
