Update (October 27, 2025) – Nextcloud Client 4.0.1
With the new Nextcloud Desktop Client 4.0.1, this issue has now been officially fixed.
According to the changelog on GitHub, the faulty Windows-VFS behavior was reverted.
The on-demand folder syncing feature — which caused the ghost folders — has been disabled.
Cause of the Bug
The problem was related to the Windows Virtual File System (VFS) and specifically to the new on-demand folder syncing feature.
In theory, this feature was meant to synchronize virtual directories only when needed.
In practice, however, it created “ghost folders” — empty duplicate directories automatically generated by the client.
Key Changes in Version 4.0.1
🧩 Bug Fix: Windows-VFS no longer creates duplicate or ghost folders.
🪟 Fixed Icons: Application and folder icons on Windows were corrected.
💾 Stability Improvement: Upgrades from versions older than 3.17.0 no longer reset bandwidth limits automatically.
🍏 macOS Fixes: Resolved crashes when disabling the File Provider and corrected localization issues.
🔄 Automatic Resync: Virtual directories created in 4.0.0 will be re-synced automatically upon first launch of version 4.0.1.
The issue with duplicate folders is now fully resolved.
Anyone still using Nextcloud Client 4.0.0 should update to version 4.0.1 as soon as possible to avoid further sync conflicts.

Update via Chocolatey
choco install nextcloud-client --version=4.0.1 --force
What’s the Problem?
The latest Nextcloud Desktop Client 4.0.0 contains a bug that causes existing folders to be duplicated inside themselves.
For example: when you open a folder named “Templates”, the client automatically creates another folder with the same name inside it — but this newly created folder is empty.
This issue has been reproduced on Windows 11 (version 25H2) using the Nextcloud Desktop Client 4.0.0.
How to Fix the Issue
Until an official patch is released, the best solution is to downgrade to a stable version of the client.
The Nextcloud Client 3.17.3 works without this folder duplication bug and can be installed in two easy ways:
1. Install via Chocolatey (Windows)
choco install nextcloud-client --version=3.17.3 --force
2. Download Manually from GitHub
You can also manually download the older version here:

Why This Matters
This bug doesn’t just clutter your folder structure — it can also cause sync conflicts and synchronization errors, especially if you use multiple devices or shared folders.
Downgrading to a stable version prevents potential data loss and confusion until a fixed Nextcloud Client 4.0.x update is officially released.
