This is the first in a series of papers in which I investigate the orbifolds of permutation-type as candidates for {\it new physical string systems} at multiples of critical closed-string central charges. Examples include the bosonic orientation orbifolds, the bosonic permutation orbifolds and others, as well as superstring extensions. In this paper I use the extended (twisted) Virasoro algebras of these orbifolds to construct the corresponding extended action formulations of the twisted open- and closed-string sectors of all the bosonic orbifolds at $\hatc=26K$. The extended actions exhibit a large set of {\it new twisted world-sheet gravities}, whose extended diffeomorphism groups clearly indicate that the associated operator-string theories can be free of negative- norm states at higher central charge.
