Here of late, I have noticed that when I open Quicken, it gives me a screen to make a choice about opening a data file. Why is it doing this and how do I get it to open the same file every time instead of having to choose it?
Check your filename length. Quicken can get picky about it if it is longer than eight characters, 12345678.QDF. Also check that there is not a space at the end before the period. Rename it in Windows Explorer with Quicken closed. Once renamed, double click on the file to start Quicken with that file, after that, it should find it on its own. NOTE: The old file name will still be in the Recent File list (File menu), but for more recent versions of Quicken, if you select it, Quicken will tell you it can't find it and offer to remove it from the Recent File list.
@Steph772001 this could also happen if you move your file from one folder to another. If Quicken doesn't see your file in the last location it was opened, it will present you with that opening screen.
