winC2D is a Windows disk migration assistant that moves installed applications and folders from your C drive to another disk using standard Windows symbolic links and file-copy operations. No modification to application binaries or registry entries is required.
- Unified file browser -- navigate drives in an Explorer-like interface with breadcrumb navigation and quick-access sidebar
- Size scanning -- calculate directory sizes with cache support for fast subsequent scans
- Symbolic link migration -- move folders to another drive, then create a symlink at the original path so everything keeps working
- Rollback support -- full migration history with one-click rollback for completed tasks
- 7 languages -- English, 简体中文, 繁體中文, 日本語, 한국어, Русский, Português (Brasil)
- Dark / Light theme -- follows system preference, manually switchable
- Auto-elevation -- requests administrator privileges on launch (required for symlink creation and Program Files access)
- Agent-ready -- ships with a machine-readable CLI for AI agents and scripts; see README.ai.md
- C# · .NET 8.0 · WPF
- WPF-UI (Fluent Design)
- CommunityToolkit.Mvvm · Microsoft.Extensions.DependencyInjection
