### Bug description

It seems like when uploading a lot of files in one go (unavoidable sometimes) that the client seems to get stuck and give out errors. I manage to work around most of them by zipping largely populated folders. However, sometimes it isn't possible.
I notice that when uploading Final Cut Pro libraries from my Mac Nextcloud client, it never seems to be able to finish it and gives out this 'Network error: 5'. I've tried researching about what it means & how to fix it but am unable to come to a resolution.

On macOS, it treats this file type (.fcpbundle) as a file and launches Final Cut Pro when I open it, but on other operating systems, it comes up as a folder and uploads all of its contents as if it was a folder.


### Steps to reproduce

Try uploading a .fcpbundle file through Nextcloud client.

### Expected behavior

It should upload all contents inside the .fcpbundle without spitting errors or freezing/crashing.
