I retrieved the data copy prior to the problem and moved it to the disk (not in a disk image). I was able to recreate the data and add attachments and lines to the register. I don’t know why 400MB would have not been enough storage to perform the tasks I needed to do, but apparently it wasn’t. I am again in a disk image, but this time it is double the size needed for the data store and backups. I have backed up a number of times and added the attachments that caused the prior set-up to crash.This may not be the best reason to use a disk image, but I find it much faster than allowing Quicken to encrypt the data.
