I always backup to a backup source and to a flash drive. But in the 2019 when I try to back up to the flash.  It tells me that I can't I need a folder.  So I put a folder on the flash and it tells me - 

QuickBooks does not have write permissions for this folder.  Please choose a different folder.

Also I don't want to have a administrator on the account.  I never have.  We are a family small business and I'm not worried about protection for the quickbooks.  How do I deactivate or is that required for the 2019 version?
