If you condense your company file, some of your data will be removed and your boss has rejected that option. What you should consider is optimizing your company file. The process will copy all data into a new company file, remove unwanted temporary data, and audit trail data to bring down file size by 25-40%. This will improve the performance and stability of your company file. Contact us in private for assistance.
