Hi Gary,

Yes thats the first place I looked.

Did not know about the date modified bit thats useful to know in future, many thanks for that tip!!

Unfortunately the last version was backed up on 6th Jan 2021
as my updates only took 15 to 20 mins xdp 17 didn't make any auto backups as i have delayed them to 40 mins

My main concern is that the file simply becomes empty at any given random time?
Kind regards
Condor
