Hello @mlurey44
Thank you for reaching out to the Community regarding your issue. You should be able to backup your file by going across the top to file > backup and restore > back up Quicken file. From there click the change button and you'll be allowed to choose the location you want to backup to between a dropbox folder or your flash drive.
If you have any additional questions please let us now.
Thanks,
Quicken Francisco
