ext4-win-driver is an open-source Windows filesystem utility that enables direct access to Linux ext4 partitions and disk images. Built with Rust and WinFsp, it mounts ext4 volumes as standard Windows drive letters accessible through File Explorer. An automatic background service detects compatible USB drives and SD cards when connected. Users can also mount disk image files through a File Explorer context menu. The utility supports read-write operations, including creating, modifying, renaming, and deleting files and directories. Command-line tools provide filesystem inspection, directory browsing, partition information, and integrity auditing without mounting. Its installer includes WinFsp dependencies, supports x64 and ARM64 systems, and offers configurable read-only mounting for safer filesystem inspection.
