The drawback of this method is that you have to read everything. For example,
if you have ten files less than 100KiB each and one file more than 2 GiB in
size, there is no need to read the 2 GiB file, is there?
If it's a one-shot attempt, I guess it won't mind a lot.
On POSIX filesystems, one has also to avoid comparing files having same (st_dev,
st_inum), because you know that they are the same file.
TZOTZIOY, I speak England very best.

I really should keep that in mind when talking with people, actually...
