I showed your post to my grandson.
He is 30 years old, and a long time windows user.
He said he has no clue what you are talking about.

Your post says eleven people have read your post, and I am the only one who has replied.
That tells me the other ten people have no clue what you are talking about.

SO MY BEST GUESS IS .. You are not saving all those things in your computers download folders.
You are saving them at some website like Facebook, or heaven only knows where.
Especially when you say you have a PROFILE PAGE there.

IF THIS IS TRUE.. A buttload of people can and have, seen all of your stuff there.
AND you need to save those things onto Flash Drives very soon, and DELETE OR UNSUBSCRIBE to wherever it is stored.
