Versions:
ext4-win-driver, published by Antimatter Studios, is a Windows-first userspace driver for ext4 volumes that enables users to browse and automatically mount ext4-formatted disks on Windows through WinFsp. Currently at version 0.2.0, with two versions released to date, the software belongs to the file system driver and disk utility category and is aimed at users who need interoperability between Windows and Linux-native storage media. When an ext4 SD card or USB stick is plugged into a Windows machine, the bundled ExtFsWatcher service automatically mounts the volume on a free drive letter in the active console session via WinFsp, and when the device is detached it unmounts cleanly. This makes the software useful for reading data from Raspberry Pi media, embedded Linux devices, or any ext4-formatted removable storage without manual configuration. Beyond removable drives, the installer registers a "Mount as ext4" right-click verb on .img files, supporting offline inspection of disk images, which suits forensic review, backup verification, and image examination workflows. The package also ships a command-line interface that allows browsing ext4 volumes without mounting them at all, offering info, ls, stat, cat, tree, parts, and audit commands for structured exploration of filesystem contents and partitions. Installation is streamlined because Setup.exe chains the WinFsp redistributable, meaning end users only need to run a single installer to get a working system. Regarding access modes, read-write is the default mount mode, while users who prefer safe, non-destructive inspection can pass --ro to the CLI or use the -ReadOnly option on the right-click verb to mount volumes read-only. Overall, ext4-win-driver combines automatic mounting, shell integration, and a standalone CLI into one package for accessing ext4 storage on Windows.
