  In this paper, the pair production of charged Higgs bosons at possible future
e+e- linear colliders is studied. Multi-jet final states are considered and the
combinatorial, hadronic and genuine tbtb backgrounds are reduced thanks to a
kinematical fit. TeV-class and multi-TeV linear colliders are likely to be
sensitive to charged Higgs bosons with masses up to about 350 GeV and 1.0 TeV
respectively.
