A fellow user, via personal email, suggested you might try the Unix
"head" utility. Something like:
head --bytes 1900m |gzip -d -c|tar tf -
I'm running low on ideas. I posted your question to the kernel mailing
list and I'll let you know if anything comes back. So far only a
suggestion for using WinZip.
