The 64-bit Offset Format

The netCDF 64-bit offset format differs from the classic format only in the VERSION byte, ‘\x02’ instead of ‘\x01’, and the OFFSET entity, a 64-bit instead of a 32-bit offset from the beginning of the file.

This small format change permits much larger files, but there are still some practical size restrictions. Each fixed-size variable and the data for one record's worth of each record variable are still limited in size to a little less that 4 GiB. The rationale for this limitation is to permit aggregate access to all the data in a netCDF variable (or a record's worth of data) on 32-bit platforms.
