    Description

      Parquet file path lengths are limited to ~260 characters in Windows environments. For example, the attached program runs successfully on Linux (provided the nested directories already exist), but fails on Windows.

      Replacing the currently used _wsopen() functions with their Win32 analogues fixes this. A patch is forthcoming.
