Hi there, lafayettecarwash.
Thanks for contacting the Community for support. I'd be happy to provide some insight about downloading your QuickBooks Online file to a flash drive.
QuickBooks Online is constantly backed up in the cloud on a secure server, so you know your data is always safe. At this time there isn't an option to send a back up file to a flash drive. One option would be to export the QBO data to QuickBooks Desktop, if you have that version already. If you don't, you can download a trial version to use for the time being. Trial Desktop accounts can be found here: https://community.intuit.com/articles/1207255-quickbooks-desktop-trial-links
I can see how it would be beneficial to be able to save a QBO file to a flash drive. I'll do my part and send the Product Development Team a message to let them know you'd like to have this ability.
You can view feature releases and product updates by visiting the QuickBooks Blog: https://quickbooks.intuit.com/blog/.
Wishing you the best of luck. Feel free to reach out to me if you have any other questions.
