That's a 26-Gbyte file.

I'd suspect a bug in the Windows implementation of `stat': it might
not support files larger than 2GB (or maybe 4GB).  Could you please
show us the declaration of `struct stat' used by the Windows port?
The interesting part is the declaration of the `st_size' member of
`struct stat'.  You should be able to find that on the sys/stat.h
header.

(The DIR command could use native Windows syscalls, which don't have
the 2GB limitation, which would explain why it works while Emacs
doesn't.)
