Linux?
интересно, как такое делается? You can force the ftp server to deliver gzipped versions of files,
and/or tar directories, by adding the appropriate suffix to the name
of the actual file you're fetching. Eg, 'get README.gz' will get a
gzipped version of this file, and 'get misc.tar.gz' will fetch a
gzipped tar archive of the misc subdir.
