On Pie.  
MZ fails to copy to microSd or usb sticks.  
It will copy a few folders at a time but whole gallery fails  
No filenames appear to be invalid.  
SD USB all pass checks.  
Reinstall did not fix.  
Config files were not found.

Ideas?  
Userspace cache?  
Hidden hooks?

Im back.

I was still thinking there could bad thumbnail files lurking around. Ive reported to vlc that their app can create humungus thumbnail fails or truncated zero length files. MZE does seem to scan for images including thumbnails even corrupt ones. Do a file search for a file named thumbnail4.  
I have found and deleted them and now MZE has completed copying my gallery.  
Hope this will continue to work and ill be allowed to post
