Bug description

The app shows a negative progress when syncing files >2GiB
I assume it uses 32 bit signed integers for the progress. Total file size seems to be tracked correctly.

Steps to reproduce

1. Upload files >2GiB to your Nextcloud
2. Check the upload progress

You might need multiple large files to get a chance to see this, depending on your Client and Server speed. I noticed this when syncing already synced files (just comparison), so I only had a few seconds to capture this.

Expected behavior

Showing correct file size
