Hello helpful GaryP and carl123,
My projects tend to involve a lot of large photographs, so many that the local or OS SSD would soon fill up if I had too many projects on the go at the same time. For that reason I have my projects on an external SSD that is backed up via SuperDuper’s software to another SSD and a spinning HDD.
Aha! I did not know that local, rather than external storage was the recommended way of doing things with Affinity.
After banging my head against some walls and walking in circles muttering incantations, I have come to the realisation that all the copies and versions stem from one original file. Applying Occam’s razor suggests the first file was corrupted in some way and the dreaded lurgy — British English for a fictitious unspeakably horrible disease; much shouted in playgrounds — spread to the others.
So, I will start from the beginning, groan, with a new AfPub file in a new folder, using the local OS disk for everything and then backup the folder to external disks.
Thank you for your help.
Sunny days,
Leslie Q.
