I am using 32bit gzip version 1.3.5. Can it decompress a .gz file
compressed by 64bit gzip? |

if you mean in terms of CPU architecture, it should make no real difference
(the Deflate bitstream is independent of the arch, so on linux x86-64, we
can still produce a file that will decode in 16 bit DOS...).
however, if you mean Deflate-64 (a version of deflate with a 64kB window
used), then that will decode on some inflaters but not on others (AFAIK, no
version of either gzip or zlib produce this format, but it can be optionally
produced by, I think, PKZip, WinZip, 7-Zip, ...).
or such... |
