I am using Quicken classic Business & Personal, version R55.26, build 27.1.55.26 on Windows 10.
Virtually all the data in my Quicken file is downloaded (via One Step Update, "OSU") from my financial institutions. I only enter transactions by hand when a transaction fails to download or I need to add a memo or other information to the downloaded transaction from the financial institution.
Recently I discovered that the opening balances in several of the accounts in my Quicken file mysteriously changed, but I didn't recognize the problem for weeks. I have several backups and I hunted through them for the last backup with correct opening balances. To hunt, I changed the backup extension from ".QDF-backup" to ".QDF" and sucessively opened the backups in Quicken.
Question 1: Is it wrong or dangerous to change the extension ".QDF-backup" to ".QDF" and then open the backup file in Quicken? If I restore a backup in this fashion and subsequently make it my new Quicken file going forward, will that cause problems?
I discovered that my most recent backup with correct opening balances was dated 2024-03-17. I would like to start with this backup and use OSU to restore my post 2024-03-17 transactions, so I don't have to enter those transactions by hand. Unfortunately, OSU has only downloaded my recent transactions, leaving a gap in my data.
Question 2: Is there a way to download all my post 2024-03-17 transactions to the 2024-03-17 Quicken backup file that I am trying to make into my new Quicken file going forward?
