Hi Midi,
The experience you've described is definitely of great concern, when Microsoft Windows updates occur. Manually adding the attachments is extremely time consuming and I can see how this would have an impact on your day. If you'd like to see a reminder to back up the Attachments folder as well, I suggest providing a suggestion to our Development Team. Customer feedback is greatly appreciated, to help improve your overall experience with QuickBooks.
If any other concerns or questions come to mind, please don't hesitate to reach back out. We'd be happy to help!
