In answering your question I assume you have created the templates on your PC
(i.e., "C:" drive) and just want to copy them to a network drive.
Your templates, which are saved as *.mpt files can be copied or moved just
as any file can be to a network drive (e.g., using windows explorer or
internet explorer). The default for where these templates are stored can be
found by selecting
Tools | Options from the menu and on the Save tab look at the User Templates
path. As an alternative you could search your local drive for all *.mpt files.
I hope this helps.
