We will continue working on this issue, but cannot speculate on when, or if, we will be able to access this new file format. In short, this means that there is no longer a way for users of some of the latest versions of Quicken to move their data to other programs like Moneydance. We've tried to access this file format, but have so far had little success. It appears that this format is intended for moving data between different versions of Quicken. Quicken now seems to offer a QXF export format. The program still seems to offer exports in the CSV format, but that format is not able to handle data as complex as an entire financial history, to successfully move it to another program. Moneydance cannot read the native Quicken file format, as this is a propitiatory file format owned and maintained by Intuit. In general, this has been the only format they have provided that is readable by other personal finance software like Moneydance.
Unfortunately, it appears that some versions of Quicken might have removed the ability to export data in the QIF format.
