Steps to reproduce

1. Sync only certain files
2. Wait several minutes for the app to check updates
3. The entirety of the files get synced
4. Delete locally all files that are wrongly being synced
5. Wait several minutes for the app to check updates
6. The entirety of the files get synced

Expected behaviour

It should not sync files that were not explicitly synced previously

Actual behaviour

It syncs all files every time

14

Additional information

GrapheneOS Logs contain personal informations that I don't want to share publicly (file names etc), hence no logs are attached

The entirety of the files get synced

By synced do you mean green icon appears on the files?

What other files are you seeing being synced? Files in other folders? Files in the same folder? etc.

[d00r5]

Yes. I decide to sync (green icon) only two files at the root of my Nextcloud (/Passwords.kdbx and /Notes.md). They are listed in the "on device" tab. But after some time, I see that the app syncs (green icon and listed "on device") the entirety (all files and folders under root /, for example /Documents/id.pdf, /Documents/resume.pdf…). The internal two way sync option in settings lists all files contained in my Nextcloud too and I cannot remove any of them.

If I try to delete locally all these folders, they aren't removed from this list (internal two way sync) and keep being synced.

13747 and #13752 may be related as it syncs everything even when no files changed and the entirety of the files

Confirming this behaviour... unwanted syncing of all files

• Lineage OS (Oneplus 11 Pro)
• latest Nextcloud Dev installed from F-droid.

Here too,

• Android 14 (HyperOS 1.0.5.0) on Xiaomi 11T pro
• latest Nextcloud DEV from F-droid (20241008)
• Nextcloud Server Version 30.0.1 RC1

Why would an obviously flawed release candidate be promoted to a standard release?
