ERF at a glance
ERF
Convert to ERF when preserving or restoring Epson-origin raw captures in an archive or compatibility workflow.
In most contemporary pipelines, it is a legacy source format to retain or migrate.
HWP at a glance
HWP
Convert to HWP when the recipient workflow is built around Hancom Hangul, particularly in Korean-language government, academic, or business environments.
It is appropriate for editable forms, official templates, and collaborative word-processing when local compatibility matters more than global default support.
For international exchange, DOCX or PDF may be easier, but HWP is the practical target inside Hangul-centric environments.
