Yeah, FLAC files. That's the only place these extra fields seem to appear, at least in the files that I receive. The current set I'm working on are actually all coming to me as APE files. I'm using Amvidia's "To FLAC Converter" to make my FLACs. I think it's so handy to have that user defined section. Tag Editor would never show those extra tags & the only other thing I had to look at tags was the dBpoweramp one. It was quite limited & wouldn't actually show me FLAC tags, but it would at least show me all the file's tags after I'd converted it to a format that was Mac friendly, even when Tag Editor still couldn't display it & I could strip it out from there.

I'm not converting my files to a lossy format any more, so it's amazing to be able to see everything, even in FLAC, & basically just strip it out manually on a case by case basis, ready for Roon.

I can see that the field editor is also way more powerful than the one in Tag Editor, so I'm well away. License bought & ready to get busy!

The Open Mode determines how files get loaded. You can access it on the File menu and from the toolbar. Do a Help>Search Yate Help and enter Open Mode. Scroll down and look for the article called The Open Mode. There's a video (somewhat dated as are all the videos) at: https://www.youtube.com/user/2ManyRobots1/feed/

There's powerful support for copying metadata between files. It's accessed on the Actions menu on the Copy Metadata submenu. You can quickly get help for any menu item via: Help>Quick Reference>Help by Menu

1. When in Album mode, Yate always sorts the files after every add. The last loaded set does not necessarily go to the top as the entire list is sorted byAlbum, Disc, Track, etc. If you set the mode to Playlist, tracks get added to the bottom in whatever order they are received. The downside is that when dragging in files the order they are given to us is not always the natural order for the album. This means albums may not be sorted correctly. Play with it and see which of the two modes, Album and Playlist, you prefer. You can also right click on any column header and create your own named sorts.

2. I assume that you're adding the artwork from a file open panel. That panel is controlled by Apple and in fact is part of the OS. By default it always uses the last open folder. While Yate can override this it is not feasible in this case. There are so many combinations of selected and unselected files that it gets impossible to figure out where to place the panel on the file system. It's been years since I've added artwork by the panel. You can drag artwork in from the Finder, Yate's File Browser, from a browser, etc. They can be dragged to the Artwork editing panel or simply to the main list of files. The File Browser can be configured to display all files via its context menu. View>Show All Files. If you see the artwork you can simple drag it over to the file list.

Hopefully this helps.

If you have a 107 disc box set and each has its artwork in a deterministic place I can easily give you an action to load the artwork.

If you do a Reply as opposed to a Submit Quick Reply you should be able to upload screenshots. I just need to know how the artwork is stored on disc.
