Description
SpaceFree scans your Windows drive and shows where the space went: WSL2 and Docker virtual disks, package caches and build folders. It tags what is safe to delete, uses the Recycle Bin by default, and runs fully on your machine. Free for 7 days.

Could you build this?
Partial Building a basic disk explorer is easy, but safely interacting with Windows system internals, WSL2 ext4 virtual hard disk compactions (vdisk), Docker subsystem internals, and the Windows Shell Recycle Bin API requires specialized native desktop programming.
What it would actually take: The application is typically written in C#, C++, or Rust with WinUI/WPF or Tauri, directly utilizing Win32 APIs (`SHFileOperation` for shell deletions) and PowerShell/WMI APIs to inspect subsystem caches. The hard part is accurately querying and invoking WSL2 disk compaction (`diskpart`/`wsl --compact`) without corrupting ext4 `.vhdx` images, interacting safely with Docker VM storage drivers, and distinguishing disposable build artifacts from critical user files. This requires deep familiarity with Windows systems programming, virtualization subsystems, and OS-level file locking semantics.
