Brandon, many thanks for your quick reply.
I’m still not sure whether the “the software is working as designed” mean:
The etilqs files being deleted if I close the WDFME process
Or the etilqs files not being deleted if I simply ‘Turn off the Computer’.
And if the software is designed not to delete the files, is there any harm in deleting them manually, eg does this increase the time needed to back up in future?
I would be grateful for your comments.
