No problem.
I have the Daz program on my C drive and the content on my
external drive.
On the Ext Drive I set up a folder called Studio. I moved the complete
content folder to Studio.  open DAZ goto Edit/Preferances or hit F2
Then Directories / DAZ|Studio Content Directories
select Add then locate and select    ?:/Studio/content

Example: Mine-
E:/DAZ/Studio/content                 Holds all Figure related  (DAZ|Studio Content Directories)
E:/DAZ/Studio_2/content2          Holds all Accessories related (Poser Content Directories)
My Drive is the
Maxtor 750gig and
MyBook 1T Net  Drive.

My content directories are about 200gig total
