Finding the unsupported file from the log

Hi,
I try and keep clean media files but on every refresh (2 minutes) I get this message below in the log.
[LibraryManager] Skipping processing metadata for an unsupported file. Message: Unknown video file type.
I have been systematically removing files trying to find the problem file but I have to many. I am thinking it is a mkv but I don't now.

Is there an easier way to find the unsupported file type?

I will update the message. For now you can change to detailed log and you should find it there.

Unsupported file identified. Thanks zip

One word of warning though once log4j.xml has been set to DEBUG the log file fills very quickly so don't forget to change it back to INFO after the problem is found.

How did you manage to identify the file, i enabled default logging but it doesn't point to s specific file

skip is in the middle, to me it looks like overlapping process logging at the same time. Which does the skip belong to?
