Can I open files without creating a source?

Yes.

You can open files in any of the following ways:

  • In Radiccio, choose File > Open (or type ⌘O)
  • Drag-and-drop files onto Radiccio’s app icon in the Dock
  • Control-click (or right-click) a file in Finder and choose Open With > Radiccio

Can I open a folder containing audio files?

Yes. You can do this from Radiccio with File > Open, and selecting one or more folders.

(You can’t currently do this from Finder or with drag-and-drop.)

Only files at the top level of the folder will be shown, and must be supported formats.

Can I make Radiccio the default app to open audio files and M3U playlists?

Yes. When you make Radiccio the default app for specific file types, those files always open in Radiccio when you double-click them in Finder.

This is strictly opt-in; it won’t happen without explicit action by you, and we will never nag or prompt you.

Here’s how to do it:

  1. In Finder, find a audio file and choose File > Get Info
  2. In the “Open With:” drop-down, select Radiccio
  3. Click “Change All”
  4. Repeat these steps for other types of audio files that you regularly open

What is the difference between “Open Files” and “On My Mac”?

Open Files is intended as a temporary or ad-hoc way to open files that you don’t necessarily want to see every time you use Radiccio. On My Mac is intended as a way to organize a music collection over the long term.

Open Files will stay open until you close them, or until Radiccio is quit. On My Mac, like other source types, remains in the sidebar permanently, unless or until you remove it.

On My Mac also supports additional features. Open Files is more limited in comparison.

Does Librarian work with Open Files?

No, Librarian cannot scan Open Files. If you wish to use Librarian, consider an On My Mac source instead.

Can I browse subfolders with Open Files?

No. Open Files only shows files that are in the top level of the folder you have opened. It does not show subfolders or any subfolder contents.

On My Mac sources can do this (with or without Librarian).

When opening a playlist, why do I need to allow access to several folders?

When opening a playlist, you may see a button that says “Allow Access to X Folders” (where X is a number). This only affects playlists, not folders or audio files.

Icon picker

This is due to macOS sandboxing, which is a security measure that Apple put in place to protect your data. Very briefly: This means that, except for those specific files which the user selected to open (either in Finder or in the “File Open” dialog), Radiccio can’t access any of your files. In general, that’s a good thing that helps keep you safe. But in the specific case of playlists, it means Radiccio can access the the individual playlist file you opened… but not the audio files that the playlist references, because you technically didn’t open those directly.

Our solution to this is the “Allow Access” button, which is an extra step before you can start playback. When you click it, you will see a series of “File Open” dialog prompts. These will already be pointing at the correct folders, so all you need to do is click “Open” each time. In doing so, you are telling macOS that Radiccio has permission to access those folders and their contents. After that, you can play the music!

Don’t worry – after you have done this for a particular playlist, you shouldn’t have to do it again, even if you open the same playlist again later.

Playlists created in VLC may not work properly

VLC creates M3U files in an unusual format that is not compatible with most other media players. They are aware of the issue and have decided not to fix it. We would not be able to fix this on our end without likely breaking compatibility with M3U files created by other software.

It’s important to note that M3U is not a formally standardized format, rather it is a de-facto standard which relies on community cooperation for interoperability. It becomes difficult to interoperate when one product intentionally does something differently than most others.

It’s worth noting that this should not be an issue when going in the other direction: M3U playlists created by Radiccio seem to work correctly in VLC (at least in our testing). So it seems that VLC can open conventional M3U files, but cannot create them that way.
