Daz 3D V. 4 files

Has anyone tooled around with Version 4 enough to know what to do of certain files (content does not appear after adding ?
I made a new folder in the following directory
c:\user\documents\Daz 3D\Studio3\My Library\ and then went into the category manager and set it as the source and when i extract the contents of the downloads i dump them into the above directory, some show and some do not. clothing, poses, and even models. some show and some do not. I download only from recommended sites that i learned of from the Daz 3D site for new users so i hope the sites files are good. Although i did end up with a zeroday bug after a install of a pose from sharecg.com i believe. Any ideas would be great on how to get them all to show.
