The Microsoft Money file (MNY) is a proprietary database format developed by Microsoft for its personal finance management software suite. This format stores comprehensive financial data, including checking accounts, investments, budget plans, and transaction histories within the Microsoft Money application. Since Microsoft discontinued the Money software line in 2009, this legacy format is now primarily accessed through archival tools or third-party conversion utilities.
