I have a 128Gb SD card for my music but every time I play tracks I get the following message - The maximum number of synchronisable files has been reached. Some tracks from the source may not be available. Does anyone know what the limit is? I started with over 15000 tracks but have reduced that to just over 11000. 

 

My music is organised with a folder for each artist and then a sub folder for each album.  Is this the best way to organise the music or should I have a single folder containing the artists folders?

I've also got a 128Gb SD card and it seems to works fine in the Columbus but a bit more iffy in the (Cupra equivalent) Amundsen.

From a quick check it appears that the file limit is 10000 but that could also include spurious windows files if you've been storing the 'master' copy there so it may pay you to check that out and delete them from the card.

I have 256GB card in use for music, which is about 80% full now. Mostly FLAC. Works just fine.

 

Thanks gents. I should have said that I have a Columbus. How does my directory arrangement compare to yours?

I just have each album in the root directory.

Thanks John, I’ll give that a go. 

Found this:

 

■ In the list, the first 1000 entries (titles, directories etc.) are displayed with the
oldest creation date.

 

I have folders organised by artist. Some atists include several subfolders, which include several subfolders again.

Tree - like architecture.

 

If you're adding music from a Macbook, it sometimes creates a 'ghost' file which can be read as a real one by the system. Before you remove the SD from the Macbook, do this...

 

Open Terminal

cd /Volumes/<card name>

find . -type f -name '._*'

This should show you all the extra little files that have been added, and then just delete them:

find . -type f -name '._*' -delete

 

Thanks for the reply but I am transferring from a PC not a Mac. 
 

Last week I deleted all music from the card and then started again. Initially I transferred a total of about 5000 files including artwork, this worked fine. I then transferred more and again at around 9000 it all worked fine. I have just checked again and I have 11,197 files including artwork and I still haven’t seen the error message, so I am now going to try adding more music. At present I have only used 72Gb leaving 47 empty.

Just upped it to 12500+ and the message is back, so unless I heard of a definite solution I’ll leave things as they are.

As I mentioned in my first post, sometimes Windows puts extra (hidden?) files in to each folder. This might have been because the MP3 track hadn't got embedded art but if the car player sees these files........ 

I'm currently deleting quite a few that had these and also checking album art to ensure they aren't 'counted' towards whatever limit we think is relevant!

I’ve deleted a lot of superfluous files, most of my music is sourced from ‘a certain website’ 😁. Lots of jpg of covers, back covers, CDs, pull outs etc. I’m not too bothered, I’ve still got plenty to listen to but it seems odd that the cars software is causing a problem when all of the data is on an independent source.

Previous Columbus on Superb 2 had limitations:

The folder structure in the connected unit must not exceed a depth of 8 levels.
One folder must not contain more than 1000°data. (degrees of data? copypaste from user manual).

 

I suspect the new Columbus has some limitations too, but they forgot to mention about this.

No idea on the 1000°data either, the manual was obviously written/translated by a non-native English speaker, there are lots of curious phrases throughout the booklet and the online version. My data only contains 2 levels, artists names and then album names.

My card contains:

561 folders

8138 files

192 GB total

A 2016 Golf I had with MiB2(?) had file limitations also - hence the comments about hidden files causing it to go mad. It also doesn't like a load of files in one folder, so I split songs into about 30 folders, few hundred songs in each, and it worked perfect in my wife's Rapid, and my Octavia vRS. Weirdly, now I've got a 'better' system with the Columbus in our new Kodiaq, it's quite slow to skip through tracks, I've come to just use bluetooth from my phone or CarPlay as it's just better.
