Split archives with 7zip reported invalid #789

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
Seen when extracting firmwares for a TV (download link below). When opening 
first package (7z.001), The Unarchiver reports "invalid archive", but not for 
all split archives.

The Unarchiver 3.9.1 on Mac OS 10.10

http://www.lg.com/fr/support-produit/lg-47LB650V (choose "mise a jour logiciel" 
under "telecharger" section, then download all 7zip parts)
-> firmware 04.32.20 packages -> invalid archive
-> firmware 04.30.16 packages ->ok

Finally fixed. File was using some undocumented feature of the 7z format.

Not that many parts of the 7z format are documented...
