Steps to reproduce

1. Add a large folder (27 GB +) containing 11.000 pictures and videos in Nextcloud desktop.
2. Upload seems to run okay.

Expected behaviour

Everything should run smoothly, no error message should appear in Nextcloud desktop. No file should be deleted.

Actual behaviour

"File is empty, although server reported x size" message appears in Nextcloud desktop. File is removed locally in my computer but exists in the server.

Server configuration

Operating system: Debian 10

Web server: apache2

Database: PostgreSQL

PHP version: 7.4.X

Nextcloud version: 19.0.0 (but pretty sure it existed also in 18.0.X)

Updated from an older Nextcloud/ownCloud or fresh install: fresh install (but pretty sure it existed too on my last installation upgraded from 18 to 19).

S3 is used as backend system. But on my previous installation I had the same problem with a SFTP external storage.

Strange thing is that I don't have this problem with any other synced folder.

Thank you !

Hi, Could you try to run the most recent desktop client and server to check if you still have this issue? The latest version can be seen by checking https://nextcloud.com/install/#install-clients and https://nextcloud.com/install/#instructions-server respectively.

If you still have this problem with the latest desktop client, please re-open the issue.

Thanks!
