Description Fabian Vogt 2014-01-03 21:37:13 UTC 
The TI nspire OS files are valid zip files and can be extracted by any zip utility such as unzip. But if I copy-paste zip:/file.zip/boot2.img to extract it, the resulting uncompressed file is corrupt. There is additional stuff at the beginning and at the end.
Example download: http://education.ti.com/de/deutschland/software/details/en/0607F21D07B14ACB9EE85E57A9C30EDA/ti-nspirecxcas_os

Reproducible: Always

Steps to Reproduce:
1. Download http://education.ti.com/de/deutschland/software/details/en/0607F21D07B14ACB9EE85E57A9C30EDA/ti-nspirecxcas_os
2. Open in dolphin with zip:/
3. Copy boot2.img
4. Compare with the result of "unzip *.tcc boot2.img"
5. The files differ



Ark works (as expected).
"unzip" says "63 extra bytes at beginning or within zipfile".
Maybe it's an issue that the header isn't word-aligned?

I can reproduce this behavior using KDE Frameworks 5.48, relocating to kio-extras.

Probably a KArchive bug though ;)
