Hi, after accidentally overwriting my folder on the computer, I'm making a copy from the last backup. It seems to work, except that I've added to my list some completely unknown disks that I've never ripped or downloaded. Where do they come from? Thanks for your help
iMac 27" - OS Ventura 13.7.1 - Nadac + Player - Cisco switch
Go to such an album, then open the three-dot menu of a track in the album. Go to „File Info“. It will show you the source / file path to the file.
Did you simply restore a backup?
Hi @KDM,
Thanks for writing in to ask about this issue. @Suedkiez makes a good suggestion for identifying where these tracks are coming from. An additional thing you can check is under Roon settings → Library. Look for the button that says “Clean up Library”/ Click it and send us a screenshot of the box that pops up. Do not click clean up library inside that box unless we (i.e. Roon staff) say you should.
Translation :
Clean 697 files: These files have been removed from the file system via Roon, or retransferred from a streaming system.
Clean 11681 files: These files are not available because the storage location they were associated with no longer exists.
(@Jim_F : yes I just restored the backup)
What I get in the file info :
The info doesn’t say where they come from… Most of the tracks have only a very short (0.04 or 0.08) duration. Can they come from system files or applications hidden in the system, as are some image files supplied (but hidden) with Microsoft or other applications or from a sound hidden file ?
Also; I can’t erase these tracks because a window inform me that I have… no authorization on the hard disk to do that (!!!)
Please help ! 
Can you not scroll down in this “Information de fichier” window?
Sorry. Yes there are more informations if I scroll down
I can follow the links, but I can’t drag and drop the file to the trash :“This file is busy”.
If I ask “show in the finder” :
Also, Roon has been running in the background for several hours. It hasn’t stopped since I asked it to rebuild from the backup…
The absence of a scroll bar in so many Roon views doesn’t make this easy to notice…
This clearly is or was copied from a macOS system folder:
Yes, it comes from the system. But I can’t drag and drop to trash…
Maybe I will restart from a external DD to access this specific system. What do you think ?
Also, do you think I have to wait that Roon stops working in the background ? I know that the recopy work is long, but I already have all my “good” lists and the tracks play well. So I don’t understand why Roon is still running.
I’m not quite sure what’s going on here and would rather wait for Daniel’s opinion before I say something wrong
Okay. Let’s wait Daniel’s advices…
Hi Daniel.
Do you or someone from the support team have an idea of the issue? And how to fix it ? Thanks.
Those are the macOS sounds. You might not be able to delete because they are in use by the macOS system. IDK. Maybe you could restore again from an older backup. Are you sure they are not in a watched folder somewhere?
Thank you, Jim. I did several backups using different backups and dates. I always have these sounds. Apparently (if I read the informations) they are in various files in the system folder. Why did Roon copy these files in the backups ?
What kind of watched folder are you thinking about ?
Thanks.
Have a nice day.
EDIT : I am learning about the watched folder. Mine is on the desktop called “MUSIC”. I see no extra ‘system’ file in that folder. Do you think I can disconnect it in the Roon settings, then call it back again ?
Hurrah !
In the Roon storage, I had two “music folders” : one is a folder on my desktop, named “MUSIC”.
The second one is a system music folder (from my user profile I suppose)
They worked together in my storage settings.
As soon as I cancelled the folder on my desktop, the “bad” files disappeared from the Roon Window.
The story goes like this: I guess the problem comes from what I did when I crashed my external music disk. It appeared when I installed an operating system on this disk (I needed a second disk to boot from). In fact, installing the system overwritten all my music files on the internal drive. Hence the search for backups to restore everything.
At the same time, I re-installed the system on my main computer (to which my external disks are connected).
In fact, installing the system overwritten all my music files on the internal disk. I didn’t pay attention to the fact that the new system saw a file called ‘Music’ on the desktop and certainly took this file as a voucher to install the invisible system sound inside. Maybe I’m right? Maybe I’m wrong?
In any case, it’s a good lesson to learn that you shouldn’t name your files just any way. A system that is being installed or re-installed can get confused. MUSIC folder on a desktop is not “music” in the system.
I would like to thank you all for your attention and help with my issue.
Have good days with good music.
Everything is OK now. Hard time to recover but it’s perfectly working now
Hi @KDM,
Thank you for your patience and we’re glad to hear you’ve resolved your issue independently through experimentation.
On MacOS, the ~Users/User/Music folder will be the default location for Apple Music. The OS will likely have automatically stored any audio files you’ve played from a file browser or any music you’ve added to iTunes/Apple Music to this folder location.
For users who differentiate between their Apple Music and Roon collections, we strongly recommended creating a second folder location as a Roon Watched Folder, as you recommended, and then importing the Apple Music library via m3u.
