Sobre os arquivos RTFComparativo de vantagens
DOCX Vantagens
- Much smaller than the legacy .doc format thanks to ZIP compression.
- Human-readable XML inside — automated extraction and manipulation is straightforward.
- Preserves formatting, images, tables, footnotes, comments, and track changes.
- Supported natively by Word, LibreOffice, Pages, Google Docs, and most modern editors.
- ISO/IEC 29500 standardized — not locked to a single vendor.
RTF Vantagens
- Plain ASCII — portable, grep-able, and diff-friendly.
- Supported by every word processor on every OS since 1990.
- Cannot carry macros or embedded code — relatively safe to open.
- Simple enough to parse by hand or generate with a small script.
- Good interchange format when DOCX compatibility is shaky.
Limitações
DOCX Limitações
- Subtle formatting drifts when opened in non-Microsoft editors (fonts, line spacing, tab stops).
- Macros and embedded scripts make older .docm variants a common malware vector.
- Complex layouts with floating objects often reflow unpredictably.
- Version compatibility matters — Word 2007 cannot open some Word 2019 features cleanly.
RTF Limitações
- Frozen in 2008 — no modern features (no comments, poor styles, no track changes).
- File sizes are bigger than DOCX for the same content (no compression).
- Images are base64-encoded inline, inflating files further.
- Visual fidelity drifts between Word versions despite the spec.
