ext4-win-driver is a Windows-first userspace driver for ext4 volumes.
Plug an ext4 SD card or USB stick into Windows and the bundled
ExtFsWatcher service mounts it on a free drive letter in the active
console session via WinFsp; detach and it unmounts cleanly. The
installer also wires a "Mount as ext4" right-click verb on .img
files for offline disk-image inspection, and ships a CLI for
browsing without mounting (info, ls, stat, cat, tree, parts, audit).
Setup.exe chains the WinFsp redistributable so end users only run
one installer. Read-write is the default mount mode; pass --ro to
the CLI or -ReadOnly to the right-click verb for safe inspection.
