Sobre os arquivos TXTComparativo de vantagens
PPTX Vantagens
- ~75% smaller than the legacy binary .ppt thanks to ZIP compression.
- Human-readable XML inside — easy to script, patch, or diff.
- Cross-compatible with Keynote, Google Slides, LibreOffice Impress (with minor drift).
- Preserves master slides, themes, animations, notes, and embedded media.
- ISO/IEC 29500 standardized — vendor-independent on paper.
TXT Vantagens
- Universally readable — every operating system, every editor, every programming language.
- Zero metadata overhead: the file size equals the character count (for ASCII).
- Safe to diff, grep, version-control, and pipe through command-line tools.
- Immune to format obsolescence: a text file from 1970 still opens today.
- Tiny footprint for structured data like logs or configuration.
Limitações
PPTX Limitações
- Animations and transitions often render differently outside Microsoft PowerPoint.
- Embedded fonts and media balloon file sizes rapidly.
- Complex layouts drift subtly when round-tripped through non-Microsoft editors.
- Older .pptm macro-enabled variants are a malware vector via VBA.
TXT Limitações
- No styling, images, or embedded structure — just characters.
- Character encoding ambiguity (ISO-8859-1 vs UTF-8 vs Windows-1252) causes "mojibake".
- Line-ending differences between OSes still cause subtle bugs today.
- No way to carry hyperlinks, tables, or formatting without a convention on top (like Markdown).
