I have recently lost several sizeable arrangements for my chamber orchestra due to the titular issue.
At certain point during work, for an unknown reason, Finale fails to continue to recognize the backup folders it earlier created itself (even thought their location or names didn't change). That prevents saving any work henceforth.
Closing the program effectively eradicates *each and every* copy of the work from hard disk (I tried finding these copies with several data restoration applications - to no avail) - including copies saved before the issue appeared. So far, no effective way of dealing with this issue has been posted on Finale forum. Where does that leave us?
Windows Finale v188.8.131.52
I have the "Make Backups when saving files" option off.
My file-saving preferences point to existing folders that are not "read only".
Using File -> Save As and replace doesn't work, either, for the same titular reason.
