Hi Robert,
Robert Jung to Hans Mangold, 20 May 97 12:07.
 RJ> In the first 64 bytes (around byte 14) you will find the word "Jar"
 RJ> surrounded by a hex '1A' and '1B'.  There is no leading prefix like
 RJ> in ARJ and PKZIP. Older JAR archives do not have this signature.
Oh. Going to have to rewrite arccheck if I want to support jar then. 
Which reminds me - is there an API, or technical format, or anything, 
available
that would allow me to extract the relevant file information from the 
rchive,
without using jar.exe to do it?
My program checks archives for mailbombs, and scans the archives internally
using its own routines (faster that way). However, because I have *nothing* 
for
jar, I can't support it... :/ ARJ is already done, though, thanks to your
documentation.
