Cannot restore from backup

Question

In Windows Quicken Classic Deluxe.  When I try to restore from backup I get a message "Please enter a valid file name." error message.

I tried copying the file, saving it with a shorter name "Backup" and placing it on my internal SSD drive (not the NAS where I normally store backups).  I have to find it through "Open Backup Directory".  When I try to open the file I get a

When I close Quicken and just try to open the "Backup" file directly, I get the following:

I'm not sure where to have the system look for the resource it needs.  I'm at a loss for what to do next.  I started trying to restore from a backup because after resetting my connection to BOA Quicken wiped out 90% of the transactions in my main checking accounting for the history of the file (going back to 2017).

Help please!!!

All restoring is doing is changing the file extension from .QDF-backup to .QDF. Restore also forces a sync with Quicken cloud which can sync bad data to your newly restored file.

Instead of restore, just copy the backup file to your Quicken folder and rename the file including the extension.

Try moving the file to your desktop and making sure that there are no spaces, or special characters (other than : \ and .) in the filepath & name..

Backup.QDF would be a good name, as Q really likes the 8.3 format, being an older app.
