Bug description

Hello,

I am using Nextcloud AIO 30.0.5 together with Nextcloud Desktop Client 3.15.3 with VFS support.

Basically it works, but whenever I select “Remove Download” from a folder or file structure, some files can randomly not be removed. I tried it several times, but not chance.

When I identify a single file, which is still in place physically, and try to “Remove Download” I receive a Finder Message:

“The file xxxxxxxxxxx could not be ejected”.

This problem is 100% reproducible on all my Macs… just the files, wich are affected are random.

Steps to reproduce

1. Download an Install Nextcloud-3.15.3-macOS-vfs.pkg
2. Add Nextcloud Instance and enable VFS support
3. Make a folder Structure available with "Download"
4. Remove folder structure from Mac
5. Check size of Folder with "du -hs foldername"
6. Result: Randomly some files are still physically available on local filesystem
7. Try to remove one of these affected files manually with context menu
8. Error Message: "The file xxxxxxxxxxx could not be ejected"
   ...

Expected behavior

After pressing "Remove Downloads", all files shall be removed completely from local device.
