There's no guarantee that st_ino will be the same as any other queryable value. Only that it will (hopefully) be unique on that disk.

stat() on Windows is just an approximation of stat() from POSIX - it's not a reliable way of reading Windows-specific filesystems.

If you can generate a collision, it may be worth investing in a solution. Otherwise, if you have a specific need to get the same file ID as fsutil, you should probably go to the native API yourself.
