samba - Jul 2018 - create QFID request

What is the function of the create QFID request.  Looking at the request
it does not seem to have any name or other discernible information.  I've
searched the web for information on how to decode the request.  The
monitor breaks down most of the block.  But the file name seems to be null.
The response to the request also does not have a file name.  But it does
show lastaccesstime creationtime lastwritetime and changedtime.  But 

for what file?  Also why would this request be made every 30 seconds or
so?

QFID is a request for file ID and volume index. It's essentially
a request for a device/inode pair. If there's no name sent then
it's done on the root of the share.
