Fast tray-first workflow
Open the app from the tray, send files quickly, and keep the window pinned open while you add more content.
MatrixIT Secure Share
Private Windows file sharing for Nextcloud, without localhost or Docker.
Secure Share is a self-contained Windows application that lets users upload files and folders, create protected share links, and manage secure sends directly from the desktop. It talks straight to Nextcloud and stores credentials encrypted on-device.
- Self-contained Windows desktop app
- Direct Nextcloud WebDAV and OCS integration
- Encrypted local credential storage
- Built for rollout to many users

Why It Sells
Built to remove friction for users and risk for IT.
Secure Share is designed for organizations that want a clean Windows delivery model, stronger privacy, and a better end-user experience than browser add-ins routed through localhost.
Folder and file sharing
Upload single files or full folders, then generate a public Nextcloud share link from the same desktop flow.
Password and expiry support
Create stronger protected links with optional password generation, expiry date selection, and one-time download behavior.
Native Windows experience
Uses native pickers, tray interactions, a single-instance desktop host, and a self-contained executable for broad deployment.
Reliable large-file direction
Uploads are handled in the native host rather than fragile browser interception, improving reliability and future readiness for larger files.
Direct Nextcloud operation
No intermediate Node proxy. The desktop app performs the authenticated WebDAV and OCS calls directly.
Private By Design
The privacy story is simple, visible, and easy to defend.
Secure Share was designed to reduce moving parts. No localhost listener, no Docker stack, no separate web proxy. The desktop app stores credentials locally with Windows encryption and sends files directly to Nextcloud.
Encrypted local credentials
No localhost dependency
No Docker required
Direct Nextcloud upload path
Single EXE deployment
Old approach
- Browser add-in depends on extra moving parts
- Localhost or proxy process to bridge requests
- More support overhead and failure points
- Harder to explain data path and trust boundaries
Secure Share approach
- Single Windows app users can launch directly
- Desktop host talks to Nextcloud itself
- Credentials stored locally and encrypted
- Cleaner deployment and clearer privacy posture
Real App Screens
Visual proof of the workflow users actually get.
These are real views from the Windows application: selection, configuration, and successful share creation.
How It Works
Simple data flow, cleaner trust boundary.
The app keeps the flow understandable: the user interacts with the embedded UI, the Windows host handles the real work, and Nextcloud receives the upload directly.
1
User selects files
Native Windows file or folder selection, plus drag and drop when the app is pinned open.
->
2
Desktop host processes upload
The WPF host performs the upload and share creation logic directly, not a localhost web service.
->
3
Nextcloud receives the file
WebDAV uploads and OCS share creation happen against Nextcloud using the saved encrypted credentials.
Secure Share UI
Upload actions, passwords, expiry, workflow, tray integration.
WPF Host
Native file handling, encrypted settings storage, upload execution, pinned window behavior.
Nextcloud
Direct WebDAV file storage and OCS public-link management.
Why Teams Choose It
It is easier to deploy, easier to trust, and easier to support.
Better for users
Simple tray access, fewer steps, and a familiar Windows workflow.
Better for IT
One executable, fewer dependencies, and a clearer support story.
Better for security review
No local proxy service to justify. Credentials remain local and encrypted.
Better for rollout
Built to be handed to many users without needing Docker, a dev server, or add-on infrastructure.
