Abstract
Geometric methods proposed by Stallings for treating finitely generated subgroups of free groups were successfully used to solve a wide collection of decision problems for free groups and their subgroups. In the present paper we employ the generalized Stallings' folding method, developed by the author, to introduce a procedure, which has given a subgroup H of a free product of finite groups reads off its Kurosh decomposition from the subgroup graph of H.
