### Bug description

This problem specifically applies to the macOS VFS provider build.
When running a disk space calculation program like GrandPerspective on my mac, it starts scanning the disk and then screeches to a halt when reading `~/Library/CloudStorage/[the nextcloud folder]`, presumably because simply probing files for their size appears to trigger a download of the entire file. I do not see this behaviour while indexing the size of other cloud storage providers which I have installed on my computer such as Google Drive and OneDrive which leads me to believe something funky is going on with Nextcloud Client VFS

### Steps to reproduce

1. Install Nextcloud Client VFS build
2. Install GrandPerspective
3. Start scanning your Macintosh HD with GrandPerspective

### Expected behavior

The scan is fast and doesn't cause Nextcloud to download anything.
