If the material was thought to be contraband (by Weiner and/or Abedin), leaving it on this computer is like leaving the heroin and machine guns on the coffee table.
Many of us learned in the old use.net days, if you want to hide a file you put it in the middle of a sub routine of a Windoze sub program. Be sure to remember where you left it or you won’t ever see it again. Oh, and change the ext. to something like *.wz$.
Leaving files you don’t want discovered on the main directory is the dumbest damn thing I have ever heard of.
