Computer Hope

 I just noticed my local disk (Y) is almost filled. Random labeled folders are filling it up. Can a virus or hacker place labeled folders in there? Or do folders have to have been placed in there by a person? The folders are filled with files consisting of videos and pics that I did not place there. Could someone else in my house have placed them there?

You really should check with anyone who has access to this computer and find out what they are doing with the computer.
