Like Richard Williams, I am not clear on what you want to do, 
but some misunderstandings seem evident here. 

-preserve- and -restore- concern temporary saving 
and re-using of datasets. Matrices and scalars 
can't be saved with datasets. 

Stata automatically creates (and destroys) temporary
files in what it thinks is a sensible directory or folder. 
You needn't concern yourself with where that is. 

Alternatively, if for some purpose you need 
to make use of different directories or folders
then that is up to you and there is no correct way 
to do it independent of your purpose.
