David,

maybe you asked for some more precise information like this (taken from one of my FY-3D PyTROLL/SatPy processing files):

# File Pattern : {platform_shortname}_{start_time:%Y%m%d_%H%M%S}_{end_time:%H%M%S}_{orbit_number:s}_MERSI_1000M_L1B.{ext}
# File Pattern : {platform_shortname}_{start_time:%Y%m%d_%H%M%S}_{end_time:%H%M%S}_{orbit_number:s}_MERSI_GEO1K_L1B.{ext}
# Example name : FY3D_20200429_011200_011300_12719_MERSI_1000M_L1B.HDF
# Example name : FY3D_20200429_011200_011300_12719_MERSI_GEO1K_L1B.HDF
# Hugo's ruler : 0123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012
# copied EMCV : 0 1 2 3 4 5 6 7 8 9 10
# EUMETCast : These files arrive as above in channel E1H-RDS-2 (HVS-1)

Best regards
Ernst
========================

Thanks for both pieces of information.

If I understand correctly, this can all be decoded in Python's PyTROLL, so that should work under Windows? Correct? If so, I'll not waste effort duplicating what's already available.

Cheers,
David
