About the POTM format
PPTX is the modern PowerPoint deck: a zip of XML parts describing slides, shapes, text runs and media. That structure is exactly why text can be extracted faithfully without PowerPoint — every word on every slide is in the package, with its slide number.
One honest limit: extraction is about words, not looks. Slide layouts, backgrounds, animations and images do not survive a text export — the output is the content of the deck, not a picture of it.
+Strengths
- ✓Text and slide order preserved exactly
- ✓Opens in PowerPoint, Keynote, WPS, Slides
- ✓Zip+XML structure is machine-friendly
!Limitations
- −Text export loses layout and visuals
- −Charts and tables flatten to text
About the BZ2 format
BZ2 applies the Burrows–Wheeler transform: slower than gzip but noticeably smaller, which is why Wikipedia database dumps and old source tarballs still arrive as .bz2.
Few GUI tools ship a bz2 reader these days, so converting the contents into a ZIP or TAR is the practical way to hand the payload to someone else.
+Strengths
- ✓Better ratio than gzip
- ✓Common in dumps and archives
- ✓Mature, stable format
!Limitations
- −Slow to compress and decompress
- −Declining tool support
Why convert POTM to BZ2?

The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.

The full directory tree is preserved: folders stay folders, and deep paths arrive exactly as they were packed in the POTM file.
