TargetExpress target files are proprietary data files created by the TargetExpress utility, originally developed by Pro-G to manage Windows shortcuts. These files store localized path configurations and metadata used to redirect or maintain application links when programs are moved or renamed. As an obsolete format associated with software no longer in active development, these files are primarily encountered on legacy systems and are generally considered safe due to their static configuration nature.
