"All Images", "All Documents" and "All Movies" in Finder will not open.

I recently discovered that other users on my macbook can see my files and photos just by clicking on the "All Images", "All Documents" or "All Movies" banner in finder, so in a bid to block this I went into "Get Info" and changed their sharing and permissions to "everyone" having "no access" just to see if it would work. it did, not even the administrator could click on them. So having established that, i changed it back to "read and write" for everyone. except it didnt change anything. i still cannot click on "all images", "all videos" or "all documents" in finder, even as the administrator. why is this?
