Yeah, renaming the folder IS NOT A FIX!!!!

The fix is to run QB update, use the reset option.... restart pc, run QB for updates to complete.

Make sure ALL updates are installed.... reboot twice if necessary.

THEN from control panel, run repair on QB....restart and the PC should stop opening lots of files from the ATTACH folder. 
The QB HUB Tool is a JOKE! Absolutely a waste of time to use!
