Cheers, very helpful.
I’m wanting to try a few things out and do a dummy run with a few folders, so I’m sure about how I want to go about it before doing the whole lot.
I trust a simple-scan will effectively delete anything I’ve changed?
While it’s plugged into your pc when you’re adding folders, I’d delete the wiim_cache folder you see there and that way each rescan will start afresh. Note that this will impact any playlists you’ve set up on the WiiM as a rescan will likely change the pointers to the files in the playlist which could occur even if you didn’t delete the cache as @simbun has reported in the past. It’s not ideal tbh…
In my experience a forced rescan on NAS music server is much better method, if it's constantly monitoring folders/files the NAS goes MUCH slower. Also if you're mass tagging, mass converting etc, it'll slow down to a crawl.
When you've done what you need ie rip/encode 25 albums then do a rescan.
That's what I do on my PI/LMS system.

Cheers.
If I don’t delete the cache, and just click on re-scan, what happens differently?
Or, put another way, what’s the advantage to deleting the cache?
Many thanks.

I still wouldn’t be sure that it didn’t re-index all files anyway and still screw up playlists you had created on the WiiM - it seems to use an internal index rather than the filename in its playlists. Given we don’t know exactly how it scans (although @simbun again might be able to comment given I believe that it’s based on miniDLNA), I prefer clearing out support files before I do anything of this nature.

Cheers. Playlists may not be necessary.
As I stream much of my music, I’m only going to be putting music I can’t stream onto the drive - the odd track/album not available on streaming, or where my CD is better sound quality.
Thank again.
In the process of setting up my Ultra and had a question about USB hard drives scanning. If I add new folders to an already scanned hard drive is another full scan required? If I switch hard drives is another scan required even if the hard drives have already been scanned? In other words if I alternated between an 2TB and 5TB drives that have been scanned is a rescan required every time there is a switch?
A re-scan is required. It won't take as long as a full scan.
The index is build and saved to a database that is stored on the hard drive itself. If you don't change the contents of each of the drives, this database doesn't need to be updated.
However, the WiiM Home app also caches the index. To be on the safe side I would start a rescan after each switch, it shouldn't take very long.
Thanks so much for your input… much appreciated!
Never mind I figured it out.
I did a rescan of the 5TB HDD and it did not correct the multiple track issue. I think there are too many folders and files on the drive. Some albums had multiple versions which could have caused some of the multiple track issues. I'm scanning a 2TB HDD now with far less folders and files. I went through and made sure there were not multiple versions of any albums. Hopefully this will work better.

I have multiples/duplicates, and so far, so good, I've had no issues.
That's good to hear. I honestly think the 5TB HDD which had over 35k songs on it was the issue. That's just an uneducated guess though. Hopefully the 2TB HDD will scan without any issues.

For reference, mine's a 1TB drive with c.320GB/17,000 tracks.
The scan for the 2TB HDD went quickly and it appears that it went perfectly. No multiple tracks on albums that did on the 5TB HDD. The ability to use a USB hard drive with the Ultra is a huge addition over the Pro and Mini I currently own.

It used to be the case that tracks were grouped purely on the album tag (so all 'Greatest Hits' tracks were grouped) but I think WiiM addressed that in an update.
I spoke to soon :-(. Going through some of my albums and there are songs inserted into albums that do not belong there. This is very frustrating. I've never had a single issue like this with an Eversolo DMP-A6. No need to scan a hard drive if it's connected to the DMP-A6 just select an album and play it. If I can't get this sorted out the Ultra will be going back to Amazon.
*Edit... actually it's the album art that's screwed up. It seems to be an issue with nine Patricia Barber SACD rips. When looking at the album folder it shows the correct tracks but with some of the songs the artwork is incorrect. The incorrect artwork is from other Patricia Barber albums on the HDD. But when I play the album the art work is correct on my iPhone 13 and on the Ultra's display. Odd issue.
