Fiio M9 Compatibility & Uploading Content 2020-01-06 18:13:51 I just ordered a Fiio M9 DAP. The documentation that comes with it is “sparse”. I found a few vague mentions that Foobar 2000 was an easy to use program with which to load music onto the M9. Can anyone suggest any published material on this topic? A few of the questions I have are:1. Must the card be formatted in the M9 before use?2. After I upload the initial content, let’s say I add a few songs. Must I reload the entire collection, or can I update just the changes?In advance, Thanks!
