Sync to Android - deleting all local files matching server? [SOLVED]

[Linwood]

I do this about once every 1-2 years, and so am sure I am doing it incorrectly, but I cannot see it.

I have 3365 regular music files in my library, and 3438 on my phone. The difference is a bunch of cleanup of duplicates, plus some metadata and playlist changes.

When I try to synchronize it wants to delete 3365 files from my phone. At least that is what it appears to be doing.

I have no idea when I last sync'd, probably at least a year.

I am trying to do only a one way sync, all regular music (I have some player piano music in a different library) to go to the phone. It LOOKS straightforward, but I must have something completely wrong. Below are the phone screen shots.

Any chance of a pointer? What am I missing?

Well, this may be a "never mind".

I found a setting that was wrong. under Devices & Services it had Music checked, but under Library -> Device it was not. I also saw that it last sync'd on 12/5/2025, so it had worked. I checked Music and did the run again and it said it sync'd, but now it will not delete any files from the phone.

I don't know why that was missing, it was clearly there in December.

It found 56 files now to delete.

Apparently that setting on the server overrides the setting on the phone. I'm not actually sure why it is in both places, but now that it matches it worked (I did have to change to "All unselected files" not just "All unselected server files" but the description made sense).

Wish I knew where that check box went, but all good now.

Is this the solution? I had to do the same thing in order for a WiFi sync to remove and album that I removed from MM2027?

What would help is which setting is the best choice? Some examples of which choice is better?

All other media files will remove all media files from the device that aren't on the Sync List selection. This includes files not in the MediaMonkey Library that are found on the device. This option is needed if you want Auto-Sync to remove files from the device that you have removed from the MediaMonkey Library.

Why does "Unselected Server Files" not work? S24+ WiFi Sync does not remove an album that removed from MM2027?

[Lowlander]

Because the file is not on the server. To be unselected it needs to be on the server.
