Thanks SickenlySweete

I change my content manager library according your suggestions

I create a scenes folder inside My Library :put for trial some olders scene inside it ,still not loading completly,i will see for new scenes

But where i put it before, new scenes were ok I have put all my saved scenes  in F: 3ddata2daz studio scene from the beginning of DAZSTudio without problem until now So may that was not the problem

I have now only one data folder in My Library and never delete manually something inside this folder

 

In DAZStudio 3 there was a way to reconstruct completly content database (scanning all the folders) i didn't see this option now in version 4
