What is an HWP file?
The HWP format is a proprietary document file generated by Hancom Office Hangul, the dominant word processing software in South Korea, widely used by government and public institutions. Older versions rely on a compound binary file structure (OLE2) similar to early Microsoft Word DOC files, while distinct encoding mechanisms are used to support the Korean alphabet (Hangul). The format is distinct from the newer XML-based HWPX and often requires specific conversion libraries for interoperability outside the Hancom ecosystem.
How to open an HWP file
Native support is restricted to Hancom Office (Windows/macOS/Linux) and the free Hancom Office Viewer. For users without this software, Hancom provides a cloud-based web viewer called Hancom Docs. Third-party support is limited; however, LibreOffice (via libhwp) offers partial rendering capabilities, and the Naver Whale browser includes a built-in extension for viewing HWP files directly.

What is a DOCM file?
A DOCM file is a macro-enabled document created by Microsoft Word (2007 and later), compliant with the Office Open XML (OOXML) standard (ECMA-376 and ISO/IEC 29500). Structurally, it is a zipped archive containing XML files for content and styles, identical to the DOCX format, but with the specific distinction that it is authorized to execute Visual Basic for Applications (VBA) macros stored within a vbaProject.bin part. This separation ensures security by preventing macro execution in standard DOCX files.
How to open a DOCM file
Opening DOCM files requires software capable of parsing OOXML and executing VBA scripts. Microsoft Word is the standard environment for full functionality. LibreOffice Writer and WPS Office can open DOCM files and display content, but support for executing the embedded proprietary VBA macros may be limited or require code refactoring. Security settings in most software will disable macros by default upon opening to prevent malicious code execution.
