QFX vs QXF - what should I use to import in quicken
QFX is a Web Connect file. In Quicken, select File-Import-Web Connect
When you select the QFX file, you will be offered to choose the existing account or create a new account. Either one will work - you can just have the transactions under an existing account or cut and paste transactions from a new account to another account.
QFX files have INTU.BID - QFX bank identifier - it can be any 'allowed' bank and you can change it before converting to a QFX file.
QXF is not QFX format and cannot be used to import transactions. It is used to transfer the whole data file from one Quicken to another.
