What does this do?
QuickBooks will limit the number of backup copies it stores in this folder. For example, if you choose to keep three backups, QuickBooks deletes the earliest backup when it goes to save the fourth backup. If you don't specify a number, QuickBooks saves all of your backups.
This limit applies only to backups you create or schedule using the backup wizard. It does not apply to other types of backups that QuickBooks creates, such as when you condense a company file, import Accountant's changes into a company file, or update an older company file.
