Re: zip could not handle files above 2GB?

Actually if the cygwin version of zip is based off of

This is documented on the info-zip website. It can be
corrected as other applications have come up with ways to
allow zip files above and beyond the 4GB limit that 32-bit
code imposes.
This is true, but I do not plan to do any rewriting of Info-Zip's code;
the web page there: http://www.info-zip.org/FAQ.html#limits explains a
lot of the limitations and caveats with respect to large files.
OTOH, rumor has it that 7-zip supports large files, and better
compression. (However, in a cygwin context it does not preserve
permisions, so you have to use:
tar --with-compression-program=p7zip ....
instead.
To that end, please try:

(I'll post an ITP on the cygwin-apps list)
