You can use BANK2OFX. It can convert your QFX to OFX. You may also do the following:
- in MS Money, try to load the OFX file and when it shows the file dialog, change the filter from *.OFX to All files (*.*) and point ot QFX file.
If it loads the file then you are fine and do not need the converter, otherwise try to load the QFX file into BANK2OFX and check if it can parse your file correctly.
QFX files are extended OFX files, so they should work as OFX files when OFX file is expected. That's why there is no QFX2OFX yet.
