More than 22.000 Thumbnails on my system

I have OSMC installed on a 16GB memory card in my Raspberry Pi3. If an update is to be installed, I always get the message that this is not possible because I have too little memory. In the system information the installed memory is displayed with 15GB, which used with 14GB.

Although I am an OSMC novice, I have seen in the filemanager, that 16 folders are created (0 - 9, a - f), in each of which more than 1.400 JPG files lie, more than a total of 22.000 pictures. Where do these countless thumbnails come from? I’m sure I do not need it all.

Can the path of this folder be placed on a network drive?

For help and an explanation I would be grateful, Ernest

The utility can be used to prune old thumbs.

You can also use pathsubstuition
I use it
4GO with 59893 files. (And Mysql (MariaDB) database)
But … sometimes you can have some issues.
i’ve issues when I scrap files. But when I restart the process it’s works.

I’m not sure why this would be better than removing old unneeded art.

I’ve more then 50thousends files store the thumbs in the box (I use 2) and not in the NAS, for me it is’nt the good way.
But perhaps the good way is to do the both; pathsubstition and cleanup;
When I scrap movies files I’ve sometimes error messages like this

I take a look to your thread, perhaps it’s part of the solution. But I go to holidays in few days,I don’t like to make changes before.

Thanks for all hints, but the problem has solved: In the folder .kodi / temp were several OSMC backup files, which occupied a large part of the memory. After I had deleted this, again more than 70 percent of the memory are free.
Thank you and best regards, Ernest

very strange… i have look on my path:

This is the same folder of kodi.log right ? I have also some files here… but the biggest it’s about 3MB…

How it’s exactly stored this thumbnails… i can see for example so many .fi files… there’s ?

We believe this is a Kodi issue or a specific Kodi function and as such you should look at addressing the issue there. We are unable to resolve your issue. If you do believe that this is an OSMC specific issue, please let us know.
