Thank you for your feedback. Our customers all have a wide variety of versions of QuickBooks on their desktops. The system I'm looking at now has these in our software audit:
QuickBooks Premier: Accountant Edition 2015
QuickBooks Premier: Accountant Edition 2016
QuickBooks Premier: Accountant Edition 2017
QuickBooks Premier: Accountant Edition 2018
QuickBooks Premier: Accountant Edition 2019
QuickBooks Premier: Accountant Edition 2020
QuickBooks Premier: Accountant Edition 2021
QuickBooks Premier: Accountant Edition 2022

My thoughts on these files and folders that are coming up in our disk usage audit is that these are patches that each version of QuickBooks has downloaded and was installed, but the software updater doesn't seem to clean up after itself once the package is installed. CAB files, for instance, are a common form of zip archive that Microsoft uses with installation packages.

I guess I'm asking for someone to officially confirm that is the purpose of these folders, and which ones I should leave alone.

Thank you again,

Brad
