I you use Linux Operating System in ur PC and want to send any zip files to ur friends using windows then u cannot use tar.gz files, so u have to use zip to compress those files.
First install it.
sudo aptitude install zip
That works for both Debian and Ubuntu for fedora or redhat download the rpm and install it using rpm command.
Then use it.
zip -r zipped_file.zip /tmp/something/
And it is done, as easy as that, and now all my colleagues will be able to read the zip file.
