This looks like an exe file, probably a self-extracting zip file, which sta=

with some executable program and after that follows the zip archive.

The jazzlib.ZipInputStream can only handle pure zip files without anything
in front. I think java.util.zip.ZipInputStream has a similar behaviour.  Th=

reason is that for those self-extracting files one normally seeks to the en=

the file, where the table of contents is stored, and then seeks back to the=

first entry. This is not possible for input stream as they are not seekable.
