According to the Product Page, these are all Props in DUF format, so you should find them in My DAZ 3D Library > Props I should think.
If you used DIM to install them, go to the Installed tab, select the item, right click, and use the Show Installed Files option. That will give you the path they were installed to.

What pack is it. Most likely it will be in Poser Format. Did you install it with DIM or manually? If manually you may need to re-import metadata

It's in My Library/Props/JoLab/Liquid Pack
I can't even find My Library...
Are you talking about smart content? The your CMS might have stopped. have you checked via the Content Directory Pane?
If you installed using DIM it will be in 'My DAZ 3D Library'
As Totte says, go to the Content Library pane, DAZ Studio Formats > My DAZ 3D Library > Props.
