Both, the VeraCrypt command line (--fs-options=big_writes) and the Vera-
Crypt GUI  (under "Settings  --> Preferences")  allow setting this mount
option.  But

   $ mount | grep veracrypt

never shows it,  initially causing me  to erroneously believe  it wasn't
set and to try finding  on the web another way  of setting it.   By pure
chance I finally found out that

   $ ps -ef | grep veracrypt

lists a  "/usr/sbin/mount.ntfs" task  which shows the  options really in
effect.  However,  I haven't yet had the time to test the effect of this
option when writing  plenty of really big files.   I will report on that
later.

Sincerely,
  Rainer
