QIF import into Quicken is not “officially supported” by Quicken support. Regardless of the support, QIF files import quite well for all account types. Simply follow the instructions provided on the converter help page, and your data will be imported.
QFX format creates “online services link” to account ID values provided on the QFX files. Make sure to enter different account IDs when converting QFX files for different accounts.
QFX files stop importing once your Quicken version becomes three years old. You have to either buy the upgrade or start using QIF format.
Overall, QIF format is somewhat easier to import than QFX (truly based on our experience).
