Three vhdx files have appeared in my network drive recently.

Windows 10.

I am a home user with a WDMyCLoudMirror network drive to allow backup and access to photos when abroad. 

Searching for large files to clear space on various drives, I found 3 vhdx files that had recently been created or midified, but not by me.  Two were created at about the same time on 14th June and are about 80MB.  The other was created (modified), with exactly the same name as one of the others on 20th June and it has 220GB!  I did not knowingly create either of these.

I have been moving and deleting many files in bulk over the last few weeks.  Recently, there have been a couple of stalls during the operation resulting in Lr showing transfers about a third complete and staying there forever. 

Any idea what might have caused these vhdx files?  Is this something Lr would do?

Can I safely delete these anyway - or might they contain one hell of a lot of photos?

And internet search for vhdx indicates its not a Lightroom Classic issue.
