Data Organizer

A cross-platform desktop application for organizing and securely storing structured data in a virtual file system.

Built with Avalonia UI and .NET 10, following the MVVM pattern with data persisted to a local SQLite database via EF Core.

Features

• Virtual file system — folders, files, and datasets arranged in a tree, saved to a local SQLite database.
• Global hotkeys — bind a file to a Ctrl/Alt/Shift shortcut; pressing it from any application copies the file's contents to the clipboard.
• Favorites — mark files for quick access; a dedicated searchable window groups them by parent folder.
• Encryption — password-protect folders. Contents are encrypted with XChaCha20-Poly1305 using a per-folder Data Encryption Key (DEK); the DEK is wrapped with a key derived from the password (Argon2id), and no password verifier is stored.
• Datasets — structured key-value records with a built-in editor for grouping and editing.
• Clipboard history — a cross-platform journal that captures plain text, formatted text (HTML/RTF), URLs, images, and files/folders. Entries can be browsed, searched, and restored; duplicates are merged, the list is capped, and password-manager secrets are skipped. Kept in memory by default, optionally persisted to an encrypted file (XChaCha20-Poly1305 + Argon2id).
• File execution — launch files with their OS-default application; execution history is tracked.
• Import & export — JSON, XML, and the full SQLite database.
• Appearance — Light, Dark, or System theme (Material Design), with configurable primary and secondary accent colors.
• Localization — English and Russian; resource-based, ready for additional languages.
• Update notifications — checks GitHub for a newer release on startup and offers to open the download page; each version is announced once and the check can be disabled in settings.

System Requirements

64-bit (x64) only. Builds are self-contained, so requirements follow the bundled .NET 10 runtime:

• Windows — Windows 10 version 1607 or later
• macOS — macOS 12 (Monterey) or later (Apple Silicon via Rosetta 2)
• Linux — a modern glibc-based distribution (e.g. Ubuntu 22.04+, Debian 12+, Fedora 42+); see .NET 10 supported distributions

Build from Source

Prerequisites: .NET 10 SDK.

git clone https://github.com/alexeyfala/DataOrganizer.git
cd DataOrganizer
dotnet run --project DataOrganizer.Desktop

On macOS, run the platform host instead:

dotnet run --project DataOrganizer.MacOS

Data Storage

All application data is stored locally:

%LOCALAPPDATA%/DataOrganizer/                                 (Windows)
/home/{username}/.local/share/DataOrganizer/                  (Linux)
/Users/{username}/Library/Application Support/DataOrganizer/  (macOS)
