Bug description

Steps to reproduce

Unsure but I think it might have to do with the always keep on device feature

Expected behavior

It shouldn't sync these files, or it should sync them at not sync them again 5 minutes later, these are a lot of files and it puts some minimal but annoying strain when I want to use the service to backup stuff and it also uses pc resources

I also run in to this bug, or maybe something similar.

Most commonly there will be newly created files (eg. notes.txt) on the local machine which NC should sync up to the server. It does sync them up, but some will show as not synced (despite now being on server) and they'll just reupload over and over and over again forever.

Screenshot of sync status showing same files, again, being synced:

In File Explorer (Win10) the blue 🔄 icon shows for the files no matter how many times they've been synced. These files are not being changed on server or local, but they keep getting synced over and over.

EDIT: I should note it does not seem to matter whether I choose "Keep files local" or "Free up space", the forever-sync bug still occurs with affected files. It's as if for some reason some data indicating the sync completion is locked or broken for the files, and NC famously has no way for end-user to tell it to 'reset' its state and recheck all files/folders, so it just remains broken with no way to fix that I can tell.

Renaming files locally does not seem to fix anyhting, the forever-sync bug persists, so it suggests sync state data associated with the files is fubar?

Probably a duplicate of #4226

Still an issue on 3.7.1

[joshtrichards]

This may have been addressed in #5474.

The other possibility that comes to mind is something bulk upload related.

Are you still experiencing this behavior?
