AB  - The diffractive open charm production is studied using data from 2006-2007, when the leading proton measurement by H1 Very Forward Proton Spectrometer was provided. The charm production is tagged by the decay products of D∗ meson. The cross section of <i>e</i><sup>+</sup><i>p</i> → <i>e</i><sup>+</sup><i>D</i>*<i>X</i>′<i>p</i> in photoproduction regime defined by the value of virtuality Q<sup>2</sup> < 2GeV is determined and corrected for the detector effects. The diffractive D* meson photoproduction cross section is compared with the hadron level MC Rapgap prediction based on diffractive parton distribution functions extracted from inclusive <i>ep</i> DIS measurements.Measurement of leading proton provides a unique opportunity to investigate the response of forward detectors for the diffractive events. Using such events, the performance of the large rapidity gap selection is examined.Keywords: diffraction, photoproduction, charm quark, <i>D</i>* meson, VFPS
