Hey @Peter_Hsieh – thanks for the feedback here.
Right now, we don’t have a simple way to just expose a file browser in Roon. It could happen in the future, but it would require some architectural changes, since you’re not simply browsing files in Roon – you’re browsing a rich, linked graph of all the connections Roon retrieves when it identifies each file.
That representation would need to be linked back to the folder structure of each file, in each folder, on however many storage devices you have configured – not impossible, but not a quick change. As @andybob mentioned, definitely make sure to add your input to the Feature request threads.
As for the other issues you mention here, Roon should be displaying Chinese characters properly, and while our extended metadata is probably going to be patchy for a lot of your content, your file tags should work fine. If you have some examples where this isn’t happening, let me know and we’ll get some files from you to analyze.
Thanks again @Peter_Hsieh!
