  We investigate the extended phase space thermodynamics of nonsingular-AdS
black holes minimally coupled to clouds of strings in which we consider the
cosmological constant ($\Lambda$) as the pressure ($P$) of the black holes and
its conjugate variable thermodynamical volume ($V$) of the black holes. Owing
to the background clouds of strings parameter ($a$), we analyse the Hawking
temperature, entropy and specific heat on horizon radius for fixed-parameter
$k$. We find that the strings clouds background does not alter small/large
black hole (SBH/LBH) phase transition but occurs at a larger horizon radius,
and two second-order phase transitions occur at a smaller horizon radius.
Indeed, the $G$--$T$ plots exhibit a swallowtail below the critical pressure,
implying that the first-order phase transition is analogous to the liquid-gas
phase transition at a lower temperature and lower critical pressure. To further
examine the analogy between nonsingular-AdS black holes and a liquid-gas
system, we derive the exact critical points and probe the effects of a cloud of
strings on $P-V$ criticality to find that the isotherms undergo liquid-gas like
phase transition for $\tilde{T}\,<\,\tilde{T}_c$ at lower $\tilde{T}_c$. We
have also calculated the critical exponents identical with Van der Walls fluid,
i.e., same as those obtained before for arbitrary other AdS black holes, which
implies that the background clouds of strings do not change the critical
exponents.
