DLP supports Haansoft Hangul for file type identification.
Both HWP and HWPX file types are part of Haansoft Hangul.
However, only the HWP file type is being detected.
The HWPX file type is not being detected.
HWPX file type is currently unsupported in DLP.
The tech doc Supported formats for file type identification states that we support the "Haansoft Hangul (Hangul 2010 SE+)" file type.
However, DLP currently only supports detection of the HWP file type and not HWPX.
Feature request (ISFR-2628) was submitted to add support for HWPX file type in a future release of DLP.
