As transactions, customers, suppliers, assets, inventory items, accounts, and attachments are entered, edited, and possibly deleted, the accounting data file for a business can grow to a size larger than strictly necessary. Data file size can be compacted by going to the Businesses page and clicking on the file size for a business:
All data is preserved.
Previous versions of Manager compacted the data file automatically when a business was backed up. But that process took excessively long when a business had many transactions, customers, suppliers, etc., causing the data file to exceed 1 GB. The current implementation allows any data file to be compacted whenever desired, reducing the size of the application data folder. The process is now entirely voluntary.
