Hi all, we're using a separate attachment storage. Is there a way to control the subfolders that are created for each attachment? Currently the path is <user subfolder>/XX/YY/XXYY<hash>. In practice this means almost every single attachment gets its own 2 subfolders XX/YY. I'm seeing users with 5000 attachments and almost 10.000 folders.

Normally this wouldn't be that big of a deal but we're using ZFS storage with metadata special device and this is causing a huge amount of additional folder metadata. It would already be helpful if we could just have a single XX/XX<hash> subfolder per user. Is that possible?

Thanks,

Cor
